i am having trouble playing A.C. I have installed it completely but the problem is when I play the game I only see white and black screen. I can hear the sound but see nothing. Please help me out thanks in advance.

Posting your computer specs for one would help. Have you also searched around yet? Most of the problems are known and probably already have a solution.

EDIT: And seriously, do something about that topic title. 'help help' doesn't exactly inform anyone what your topic is about.

soory dude wont happen again

As you've found the help forum and posted there, and your questions have been answered, I'll lock this now.

 although I doubt if you'll be happy with the answer to your problem
