to the forum.

Tell us more about your problem: Did you make any changes yourself? Have you installed any mod?
Did they never work or have you been able to play a few already?

You should also activate -show_err:

Right click on your RTW-shortcut on your desktop. Select properties.

Go at the right end. Add: " -show_err" (Without quotation marks, but with space). Then press OK.

Start the game again, and you should get an error message.

Post the error message.

However, reinstalling should always do the trick, have you tried it already?
