There is a big problem with content: you purchase video files legally and can't watch them later on. And you just upgraded your system or got a new one. Why should it be that way?

You can't remove DRM protection without licenses allowing you to play your files. The only solution to this problem is to re-acquire licenses from Movielink. If they won't provide you with new licenses, let everyone know about it! And boycott any service providing DRM-protected content!
