Client Crash on Server Join

[zx636ninja]

My friend and I made our own modpack and server for the modpack. We are having trouble joining the server because we get a crash report: http://pastebin.com/xk5jtQa2 only on the client and not the server. If anyone can help, it would be most appreciated! Thanks

You installed a 1.4.6 mod.

Do you know which one?

The one with a 1.4.6 in its filename maybe?!?

Either:

a) google all of them and make sure they're updated for the version of Minecraft you're using

b) start removing things until it works

c) remove everything and start adding things until it works
