Removing Mods Crash!

[Xedearnal]

In preparation for the 1.5 packs and possibly future packs I decided to take redpower and wireless redstone (due to another problem) out of the FTB ultimate pack. It is seamingly fine until I load up my world. When I do I get a crash:

Minecraft has crashed!

--- END ERROR REPORT 31570a9f ----------

I had to remove a portion to fit with the character limit. It just listed the mods.

Okay this one is probably because of the NEIpluginsRedPower in the mods folder. Disable that and it should work. Any further error you might need someone else to help.

THANK YOU! You were correct! It fixed it. Though I was rather disappointed as the amount of stuff redpower added that I lost. For instant I didn't realize rubies/green sapphires/sapphires were part of redpower. Nor did I know about the vorpal enchant and the project tables. Looks like ill just have to live without them. Though I know innimbus recreated the microblocks so that's something.
