Windows .exe Ultimate Crash

When I try to join my world, sometimes it stops at Loading world and it gives me this error:

2013-03-31 16:49:24 [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.

Does anyone know a solution for this?

Please post your entire client side console log on pastebin.com and link your paste URL here. This is the other window that is opened by the FTB launcher. Please post any and all other logs you can provide to pastebin.com and link those as well. Logs are much easier to read when uploaded to pastebin. To prevent future issues, such as pastebin flagging your log as spam and deleting it, it is simplest to create an account on pastebin.com and use that account to upload your logs.

1. Update your java
2. Take the spaces out of your Feed the Beast folder

This would be a great thread title for a rant about Ultimate - if that was possible, just saying.
