Looks like it tried to launch but didnt have enough ram. try allocating another GB. (Options tab)
Also, for the others who will view this, is it the Lang outofmemory or the ic2 rendering issue?
(Check line 3390)
EDIT: Your running a 32 bit version of windows. You might not be able to get enough resources to the pack along with everything else your computer does. You might want to try buying a 64 bit version of windows. Its expensive, though. You should try allocating more memory first. If that doesnt work, try a smaller pack, like FTB lite 2.
