Windows .jar FTB ULTIMATE Crashing On single but not Multiplayer

[Lithia]

Hello everyone
I have been having some troubles loading my FTB lately
My PC Specs are
Windows 7 Home Premium 64-bit
RAM = 4gigs
Processors are 4.40GHZ
and 2 graphics cards
Both ATI Radeon 4500/5100

Now
All the packs work on singleplayer and multiplayer and get around 120FPS

FTB mindcrack use to work on Single and Multi but now it wont Boot on single anymore

FTB Ultimate is the same it works on multiplayer But! Its never worked on single

ive gotten my ERROR logs from my .minecraft and here they are http://pastebin.com/kmVYJB3X

Ive tried the

-XX:MaxPermSize=256m ect ect in advanced settings

It doesnt help it just changes the error every time

Any idea whats going wrong?

I'd suggest updating Java to 7u21, then post a new console log if you're still getting crashes.

Another thing that may work is to delete everything associated with FTB, including the launcher, the ftblauncher folder in appdata/roaming and the install folder listed in the launcher options, then redownload FTB. Back up your saves before trying this option!
