Hello. This is unbelievable. WM Player 10 won't play anything without license. I have several dozens of legally purchased CD ripped and converted to mp3 so I can listen to them on computer and now, after upgrade to Windows Media Player 10, I can not play them and I get the message: “Cannot find the license for this file”. What am I supposed to do?
Hello. Welcome to the DRM world. You can find encouraging information about this problem on Microsoft knowledge base. According to them, if you do not have back up of license (and you probably don’t, you will have to rip all songs again from CD and obtain new license this way. I hope this answer helped you a little bit.
