When I start Tekkit it loads up and I can log in, so far Normal then when I click Play, it goes off the start screen then 20seconds later it comes back up, I have tried with 32bit and 64 bit and I have also tried 526mb and 3gb to see if it needs more or less gb to start up but nothing... I have also reset my laptop to factory settings but now nothing... Please help Thanks ~Max
