Premiere Pro CS6 Crashes immediately on start up

So, everything was going fine until yesterday. It suddenly has stopped working. When I try and turn it on, the "loading" screen comes up for barely a second and then dissapears, and the program never turns on. I tried reinstalling, deleting the preferences, even deleting some other programs but nothing works. I recently installed dxtory, but it worked after installing it and suddenly it doesn't. I removed dxtory, still doesn't work. I tried turning my pc off and on, etc, all that kind of stuff. Please help, I am a Youtuber and I need quick help
