That's a graphic card issue.
Just minimize the game once and maximize agan.Screen will appear.
Happens to be everytime and sadly i cannot update my graphic card drivers because sony vaio are too lazy to update them since 2010.
I have the same problem.... I have a new lapop there si 3 days old, and have a Nvidia Geforce GT 650M 2GB.... Soo I can run the game and I have the newest driver and alle that.....!
I can see that there are many there have the same problem....
Are they trying to fix it? It is so frustrating because I dont know how to fix it, and I have not seen that they are trying to fix it????
(Sorry for my bad english)
