Spanish Lessons on 720

I have a problem I can't seem to solve. I have searched the forums but find nothing. Maybe some here can help me.

My best friend and her husband are moving to Mexico and I don't speak Spanish. I have many programs but just haven't mastered it yet. My daughter and I are taking a conversational Spanish class right now but I wanted some extra help, so I re-downloaded a program from MobiPocket "Spanish with Ease" I bought several years ago. Here is the problem:

When I click on the volume button within the program, I get the error "There is no application associated with 'playlist'. Run the application first, then open this file from within the application." If I go to Windows Media Player, the WMA sound shows as "temp1_rec1" and plays fine. However, since there are hundreds of sounds within the program, it would be nice if I could make it run with no playlists.

Can anyone help me?
