====Loading Terrain Freeze====

[AdixGaming]

So I've had this problem for a while and I really need help! Whenever I start any mod pack in the FTB launcher it is always smooth nothing wrong, so after I create a world it gets stuck at this:

Loading World​

Building terrain​

This is the console after it gets stuck:​

2013-04-13 11:01:53 [SEVERE] [ForgeModLoader] The ForgeModLoader state engine has become corrupted. Probably, a state was missed by and invalid modification to a base classForgeModLoader depends on. This is a critical error and not recoverable. Investigate any modifications to base classes outside ofForgeModLoader, especially Optifine, to see if there are fixes available.
