I've been having a white screen CTD, and it started right after messing w/ the application ingame when trying to change alpha and setting it to 0 accidentally w/ a typo. Any help? 
Edit: I'm not sure what the issue is, just that that's the last thing I did and the moment I did that, the game crashed and upon subsequent startups, white screened, became nonresponsive, and crashed without explanation as to why
