Title: Tekkit crashes when I try to log on to a private server. Help!

Version: 3.1.3

OS: Mac OS X Lion

Java Version: (build 1.6.0_33-b03-424-11M3720)

Description of Problem:

When I try to log on to a private server it either crashes immediately or lets me move around for a bit and crashes. I tried deleting every thing off of tekkit even the .jar file and re-downloading it but nothing worked. I don't know if it is a corrupted .jar file or the mods. Please help.

Thanks
