macrovision cleanup.exe / video games

Since installing comodo FW some of my games (BF2, COD2) won’t run. I used process explorer to check the running processes and under the game is macrovision cleanup.exe (the game is shown as running in process exp. but will not start). Also running was comodo agent service and appeared to be corresponding in CPU usage to cleanup.exe. I did some googling on cleanup.exe and appearently it’s some sort of copy protection and one report said it conflicted with some firewalls. Could comodo be interferring with the games?
