Game do not start after update

Hi,

after yesterdays update game is not starting at all, just black screen window and cannot do nothing only close it. I did reinstall the game and it didnt helped.

Any ideas what can I do?

I emailed to raise a bug about this. I was given a list of things to try and then look at forums.

The game still does not work and all i know now is there are a lot of annoyed people out there unable to play the same game I purchased yesterday.

Which operating system?
