Windows 7, Zune and DRM removal using Aimersoft DRM converter

[Darth DRM]

Would appreciate it hugely if someone can help provide a solution to the following....

I'm running Windows 7 and have Zune installed. I've also been using Aimersoft DRM Converter to strip DRM from the Zune wma files but constantly run into media usage rights issues (although for some reason it does work with some wma's). Is there a workaround?

If nothing can be done I would also appreciate it hugely if someone could describe something which works to get rid of the DRM in Windows 7, and provide active links to download any files required to achieve this.

Cheers!
