Duke, thanks for your Reply.
Installing DirectX 9 doesn't help either. My Problem is, that I uninstalled WOFF before I changed my Operating System.

I made a fresh Install of Windows 7, without any Drivers or Games or Programs, then installed Windows 10. My thought was to have a complete fresh Operating System, without any old Drivers, everything is new installed.

So after that I installed WOFF, and it didn't work. Game crashed when loading a Mission. And now after several hours of searching the WWW about this Problem, my suggestion is that the old CFS3.exe is NOT compatible with Windows 10, if you make a fresh Installation. There are many CFS 3-Gamers outside in the World, who have the same Problems.

Haven't found a Solution yet, but I will try further.

So please, beware if you make a fresh WOFF-Installation when using Win10. Seems it is a Problem with some Security-Updates.
