Game won't launch

The game won't launch for me now. It just stays at a black screen when I launch the game. I can't close the game either. If I try forcing it to close the screen goes white and does nothing. I have to restart my computer just to get it to go away.

Nvm figured out what the problem was. I have norton antivirus and it was blocking the program. It seems to do this each time the game gets an significant update. Normally it prompts me saying so, but for whatever reason it didn't this time. I had to go in and add it to my allowed program list.

[[75123,users]] I want to say thank you for sharing your successful resolution. I have a Windows pc now so, if I ever want to play DD2 on Windows operating system. I will know what to do, whenever I encounter that problem. This will also help others a lot. 

Glad I could help.
