When I go to play one one of my saves, or to start a new one, all I get is the dirt screen with no text on top of it. It stays there forever unless I close the window. I've uninstalled and reinstalled minecraft a couple times now but it doesn't seem to be helping anything. Originally, I was having an issue where the game crashed at the 'Mojang' screen, but reinstalling the game seems to have fixed that issue.
I think what started all this was when I had a bunch of mods installed, a FTB pack I think it was. Somehow, I think the mods made my entire computer crash, leading to a bluescreen. This hasn't happened again, but ever since then, I have been having these problems.
