Hi! I downloaded MPC months ago and it worked great - but now it suddenly disappeared from my play options, when I want to open any kind of video file (even browsing doesn't work). Any idea what might have caused it?? The player is still on my computer, it just doesn't register when opening a file... I even downloaded it again - newer version - and it's the same! Any help would be greatly appreciated, I'm at my rope's end here!
