Win10? If so, just rename the nfs.exe file in the Prostreet folder to something else. In my case I renamed it ProStreet.exe, but you could call it Super.exe if you wanted to as long as you don't rename it nfs or NFS. It will then work. I think that Win8 has the same problem too if I recall correctly. ELSE, you MAY have patched the game with the wrong patch, as there was an American and an European patch. If you installed the wrong patch, the only way to fix this is to uninstall everything related to ProStreet then reinstall anew.
