Mov.file - Video Clips Will No Longer Play

I have movie clips copied to DVD disc which has always played fine with Windows Media Player. I installed mediaplayercodecpack.com yesterday (now uninstalled), and I can no longer play the video clips. The error message reads ' windows cannot access the specified device path or file. you may not have the appropriate permissions to access the item.' I'm using windows Vista. Can anyone help as these are important movie clips of a family wedding and I need to get them back somehow.

 

The problem is probably related to installing/uninstalling mediaplayercodecpack.com but, the message doesn't correlate to that.
Install Media Player Classic Black Edition, and see if you can play the files.
