I suppose my best bet is downloading them again, although it is strange. My Assassins Creed clips work just fine, so I don't think it's my computer :/
So I just downloaded some openings and cutscenes for my AMV, and when I imported them on Movie Maker, I tried playing them but it stopped after two seconds and it was all black. I'm pretty new to all this, I only made one music vid for Assassins Creed a few days ago, and it was the same file type as the KHvids, so I don't know what the problem is. Help?
