    I just downloaded the FTB client and I wanted to try out the FTB ultimate mod pack.
    After launching the client, in the log it gets to "mc = class net.minecraft.client.Minecraft" and it just stops there and it does not launch the game.
    Nothing happens after the last line of the log.

    Try taking the spaces out of your FTB Clients folder.

    I tried renaming the folder to "FTBClients" still its the same problem.
    Alo what the files thats supposed to be in my minecraft folder inside Ultimate?.. I only have the minecraft.jar file..


    I tried a force update and installed the modpack again (FTB ULTIMATE) and now I get this error.

    (I'm getting an error saying i exceeded 10,000 words.. o_O so I had to use pastebin..)

    I think the problem is with updating the bin folder of minecraft.
    Also while updating my vanilla MC to 1.5.1 i had trouble downloading from mojang servers so i had to download every file of the bin separately.
    So if anyone can upload the bin file alone(1.4.7) it would be really helpful.

    UPDATE 2:
    If I try force updating it the mod pack (32mb for Ultimate) is downloaded within 8-10 mins and now it starts to download minecraft jar files.. and gets stuck at 2 or 3%.

    So to fix this i tried copying the minecraft jar files(lwjgl.jar,minecraft.jar,jinput.jar,lwjgl_util.jar) along with natives of a vanilla MC 1.4.7 to the Ultimate folder in FTBClients.Now when I try launching it gives the same log as in my first post ending with "mc = class net.minecraft.client.Minecraft".I'm really confused now.. o_O..

    Actually, we prefer that you use pastebin.

    Now can you please look into it?..

    I've got no idea about this error. When I had it, redownloading fixed it, however that doesn't seem to be working for you.

    GalXiOn New Member

    Hmm...Can you please tell me what are the contents of ftblauncher/modpack/Ultimate/ ?
    and if its not much trouble can you upload one of the modpacks alone or is there a way to download the complete modpacks manually? ( i.e ultimate .. lite.. etc..) I can put them in my FTBClients folder and check - since im having trouble updating.. it MIGHT solve the problem.

    The contents of ftb/Ultimate/minecraft should look like a standard modded .minecraft folder. It should look something like this: http://puu.sh/2sqdV

    I'm not legally allowed to upload a copy of any mod packs unless given permission by Mojang and the maker of every mod involved.

    I only have bin,coremods,config,mods...>.<
    Is there ANY way i can download the full ultimate modpack folder?... I'm still stuck on the 2-% on the downloading of minecraft.jar in the process on force update and for some reason its not showing the link from which the file is being downloaded from, unlike for modpacks..where it shows the link as "http://www.creeperrepo.net/direct/FTB2/.....".

    Also do you have any idea why i am getting this error(it is after I manually downloaded the jar files of bin folder)

    Its happening to me too, for some reason. Also, it seems to freeze my internet.
  12. GalXiOn

    GalXiOn New Member

    Umm.. you can get the direct link for pretty much any modpack from the log :p.. and I tried that also but the file does not include the bin folder which has the minecraft jars - which seems to be my problem >.<
    I need a working bin folder from a fully working client. :(...

    Well I have no idea about the internet freeze thing but lets hope we get a fix for this :(...

    Ah, my bad, i misinterpeted the part about not showing link.
    Anyway, you could try to figure out if it's caused by FTB or not by opening the vanilla minecraft launcher and check the forced update option before launching.
    If it downloads then it's likely FTB somehow, if it doesn't then it's likely something on your computer or local network.

    Well I had the same problem with vanilla MC - updating to 1.5.1 took about 2 hrs lol.. the speeds were mostly <1kbps while my internet connection is 4mbps... >.< maybe my network can't connect to mojang servers properly.
    Unfortunately I haven't found any way around it.. i'm still searching for it.

    Well, for me, vanilla minecraft updated quickly, its just the ftb pack jars that aren't downloading (the maps and texture packs download as normal).

    About the first link - I tried disabling the antivirus and firewall settings its still causing me the download issue.
    I have no problem downloading from creeperhost (modpacks).I'm stuck at downloading the minecraft jar files from the mojang servers so I'm searching for working bin files.

    Really? You can get theat by coping your bin folder from your mincraft directory over to your feed the beast directory. As long as you have not updated vanilla minecraft past 1.4.7

    We can not send it to you as that would be giving you the game.[DOUBLEPOST=1365026937][/DOUBLEPOST]Follow the first seven directions under the fix one section on the link in my signature about leaking worlds.
    If that does not work, please read link in my signature about log files. :D

    Go to ftblauncher/modpack/ and then simply delete the ultimate folder (copy your configs first if you have custom configs.)

    Start your ftb launcher and redownload ultimate. Should fix your problem.
