Serial don't work after update.

Statyk is right. We can't give out serial numbers. If you bought the game from a friend or random person than chances are, they've already used the key.

I reinstalled it. To the normal version. But still got the black screen bug.

Well, that's really all we can do. It looks pretty clear that you got the game from an untrusted source and as a result, got an already used key. If you wish, post a new thread on the black screen bug. But otherwise, this thread is done.
