I upgraded from Powerdvd 5 to Powerdvd 7. Now after I restarted my computer. None of my dvds will play on the player. The application crashes. I then noticed none of my mpeg and avi files wont play in wmp 11. I uninstalled Powerdvd and wmp 11 and reinstalled my copy of powerdvd 5 and wmp 10 and still nothing. Also, when i open my movie folder i can usually see a picture of the start of the file, but instead it shows the application icon for that file. Any help would be appreciated.
