I have 60 plus wma tracks downloaded during 2009/2010 from Napster.
When I try to play any of them I get a message indicating that the DRM
information cannot be accessed. When Napster was acquired by Rhapsody
I backed up the DRM licence files via Windows Media Player.

Unfortunately MS have since amended Windows Media Player and it can no
longer access backup licence files and Napster/Rhapsody are not
interested in the problem.

Given this I appear to have just two options - purchase replacement
tracks or buy an audio file converter that is capable of removing the
DRM constraint.

In the event that anyone is able to recommend such a converter (or an
alternative approach) I would be very grateful.
