Hi everyone!

I know I have a custom modpack, not a FTB one, but since many of your are skilled at creating, working with, and using mod packs, I have a question. Normally my 1.6.4 servers just start up normally, but ever since I created this new modpack with a few more mods and a few different ones, I have been getting this error. I have tried to launch the server with no mods, and it works fine. But when I add the mods folder back into the server folder, the I get this error:

Here are the pastebins:

server log
crash report

and here is the mod list, if there are any ones that stand out that could be causing the problem.

Are you trying to launch the server while Optifine and Zan's Minimap are in the server mods folder? If that is the case, I suggest removing them since they are client only mods.
