[CRASH/CLIENT]- Doesn't load me into the game at all

Last night I encountered a bug after my game crashed; I tried loading up again to see if it would let me back in but instead, it gave me a black screen indefinitely. I couldn't alt-tab to get out of it, in fact it wouldn't respond to any button inputs what so ever, and the only solution to even work with my computer was to force a shut down. This morning I tried to repair the client, and that didn't work, I tried to uninstall/reinstall and that didn't work either. The client itself works, but everytime I try to get into a game it just gives me the same black screen and nothing else.
