Windows .exe Launcher Won't Load Mods

[Bloquemaster]

Hello there,
I was playing on a direwolf20 SMP when I pressed a ? button on the spell image select button for Ars Magica 2. It crashed my game, and when I open the launcher the mod packs aren't loading as they usually do when I start it. Here is the error code from the console:

Loading modpack information for modpacks.xml...
Exception reading modpack file: com.sun.org.apache.xerces.internal.impl.io.MalformedByteSequenceException: Invalid byte 1 of 1-byte UTF-8 sequence.

I tried re-installing the launcher completely, but with no luck.
Any help would be appreciated
Thanks!

I'm getting the same issue looks like the issue might be server side.

 

[Chaos5061]

Operating System, bit type: Windows 7 64-bit
Java version/update, bit type: Java 7 Update 45 64-bit
Launcher version: 1.3.2
Completed the troubleshooting guide (y/n): y
Console log, pastebin.com link: http://pastebin.com/hsLHdeEB
Description of the problem: Used the private code for the Monster pack to download and install it. Next time I went to launch the launcher this happened.

(Optional information if issue involves download problems)
Anti-malware software and/or firewall:
Location you're downloading from (per Launcher's Advanced Options):

It can't be, it's the launcher having the problem, not the server.

It can't be, it's the launcher having the problem, not the server.

I think he meant server side as in the servers hosting the modpacks and all that information. I'm getting the same error as well and have no done anything different to the launcher. Was working fine a few hours ago.

Uninstall all versions of Java. Restart your computer. Then reinstall from here.

 

[Y_sukai]

been running the launcher fine up until now, now I get this

Uninstall all versions of Java. Restart your computer. Then reinstall from here.

I have not been able to re-create this error so far.

Same here. It stopped working when I updated (launcher) just a few minutes ago. Guess it's time to go to bed

I just merged all 3 threads having the same issue.

Please make sure you're all doing this:
Uninstall all versions of Java. Restart your computer. Then reinstall from here.


Per @Viper-7: Close your launcher completely and try again.

 

[spidey1958]

Tried by other 2 machines why rebooting and re installing Java on main machine both get same error.[DOUBLEPOST=1387862392][/DOUBLEPOST]Now working on other machines

 

[NoYouCantHaveMyName]

It's working again. I'll add that I did nothing (didn't reinstall Java etc.) so it must have just been a problem with their hosting server thingies.

 

[Y_sukai]

well problem seems to stop on his own didnt do anything and it started to work

 

[hyper1on]

I uninstalled / rebooted / reinstalled java, works now. Thanks for your hard work Ashzification!

Per IRC, it appears to have been just a little blip in the system.
Rebooting the launcher appears to work for nearly everyone.
Locking this thread.
Thank you all for your cooperation
