Hi L. Taviani,
According to your description, could you please tell us that what you have done before this problem firstly occurred.
What happened when you start this game? Is there any error message pop up? We could go to event viewer to see the event log, it can assist us to diagnose problem.
I suggest to reinstall DirectX9.0 in clean boot mode, some users solved their issue by this method.
Last but not least, since problem occurred few weeks ago, we can try to execute a system restore to test result, please note save your important data in advance.
Hope my clarification is clear.
