Did you manually update the server? The log says it all, 'cpw.mods.fml.common.DuplicateModsFoundException'

There are a lot of mods that are the same, but have different names in the mods and core mods folder. Here is an example: MiscPeripherals has these two names miscperipherals-3.1c.jar and MiscPeripherals.jar

I suggest backing up your save world and deleting the copies. You could also delete the mods and coremods folder and re-download the server edition.

That is the way PedPower says it has an ItemID conflict. If you are using the client to connect to the server you need the same configs as on the server. Copy over the configs from the server to your client. If you still get this error you need to change some ItemIDs. Hopefully copying the configs from the server will fix it.

I do not see any added mods. Did you add any? Is this a new map or an existing one? I want to make sure to give you the correct advice going further.

So you are starting out fresh new map on your server? If so then I suggest this. Re-download your client modpack to what ever version you want the server to be on, do not save your configs. Then delete the mods in your coremods and mods folder and delete your configs from the server. Now copy over your mods folder, coremods folder and config folder to the server from the client. Now start a new world. This will give you the configs from a fresh copy of Mindcrack and have no conflicts. Sorry for the extra work this entails.

Not to be rude, but did you read any of my posts completely? RedPower is having conflicts with the other mods ItemIDs. If you get a fresh copy of the modpack on your client you will not have any conflicts in the ItemIDs and this error will go away.

This is your error log not your console. Follow this guide to get it.

So you downloaded a fresh copy of Mindcrack and copied over the mods, coremods and configs over to the server? Is this error in Single Player or when you try to connect to the server? There should be no conflict with ItemIDs unless you chose to keep the old configs when prompted.

Well I believe I have the possible solution for your problem. GregTech and his 'protection' code are causing the error. If GregTech finds you are running it from a folder that is either named tekkit or technic or has tekkit or technic anywhere in its path it will crash with an error. Uninstall again and put FTB in its own folder without tekkit or technic anywhere in the path.

Edit: Use this guide to install FTB.

That was the ticket, thanks so much, and thanks for being so patient with me!
