This mod works alone on its own, but when you use other mods alongside of it, it doesn't work. Mods I use are Too Many Items, Single Player Commands, and Reis minimap. I used to use this and install this mod with those in previous versions of MC from 1.7 up to 1.1 which still work but this version doesn't work with them anymore all of a sudden.
Edit: I actually narrowed it down to it being TMI. Is there something that was changed or left out with the modloader or whatever added to this version because TMI is probably crashing due to the fact its trying to use modloader, but cannot most likely. the game error screen disallows me from reading what the error is because it just exits out of the game disallowing to scroll through the error log.
