Game freezing

Ever since the new Alice update every time I click E to open my inventory my game would completely freeze up. In the log this would pop up when it freezes:

2014-06-17 11:32:20 [SEVERE] [ForgeModLoader] Unable to launch

Caused by: java.lang.OutOfMemoryError: PermGen space

I don't know what this means and if it isn't enough info I can try to find the crash log. (forgot where it was)

Anyone know how to fix this?

 

I literally just figure it out XD I had to increase the PermGen, thanks!
