it shows up at taskbar etc. and i can open it but if i presss start nothing happends it just stays off no matter how many times i press start.. :S but before it worked fine

any 1 had this problem and knows how to fix this shit ?

You probly need to get a new license or something.

Roll the system clock back to a couple months ago -> pres play -> see if it works. If it works you need to get a new license. If it doesnt work then idk.

i tryed reinstal and now it works again. if it stops working again after some month then ill try what u said thanks :D
