I am not using the No Intro fix, but didn't need it since they all play fine. The NOCD patch appears to be working fine too, along with one of the trainers I grabbed here...
Maybe it was a bad install, or you have something running in the background? I would think it could also be an issue with the NOCD patch. You might want to trying another one, if you made a backup of the original exe. Otherwise, it sounds like a re-install would be in order.
