There is my crash log, so if possible could u tell me what's wrong with my minecraft, and why can't i use Ars Magica and Modularpowersuits mods? (I know they're 1.6.2 mods but they work on a youtuber i'm subscribed to.) So please post all possible info about this here. And by the way my minecraft crashes sometimes when i open something in minecraft, like if i open thauminomicon my minecraft crashes and it says something about shutting down internalserver or something.
