Game Crash Central.

So, I have never had a problem playing League until tonight.

I have gone through microsoft to try to fix the error, uninstalled the program, reset my drivers, uninstalled my drivers, everything I can think of. The game played fine last week, but is having problems now.

The launcher is fine, but when I start a game, my character never loads in the screen. If I alt+tab out and back in, the screen is just forever black. I looked in the forums and tried to delete the folder in lol_game_blahblah>releases, but to no avail.

It seems to be running in the background, but it is only a black screen to me. Any help would be greatly appreciated.
