So up until a few days ago Media player worked fine, a day or two later it won't open the majority of my files. It constantly crashes because of a Data Error Prevention error. The only think I've done since then is uninstall a webcam and install a PC game. My only thought is that somehow a driver I need got associated with the webcam and was deleted but that doesn't seem likely.
I've also tried allowing the DEP to ignore Media Player but it still crashes when I try to use it. The odd thing is that some media files will play, music works and a few movies too but the majority of my movies won't play without crashing.
I've tried uninstalling and reinstalling windows media player but that didn't fix it either.
