I think if you write to mdna games (aka Michael from Sweden), he will help you out. I seem to remember a similar thread here where some people had similar problems with some older mdna games.
I'm not sure what solution Michael will use, but If I remember correctly, it could exchange of a file someting like that...
Karsten has a good suggestion. I googled this error message and it was suggested on one thread that some Windows Update might possibly have caused this problem. The experts here might be able to suggest a fix, too.
