Convert .tmp music file to mp3?

Can't you just try and get Amazon to get you the .mp3's back, coz you purchased them anyway. The customer is always right. You might be able to play these on Audacity, but since it's a Amazon format you may not be able to convert it back to mp3 anyway. Google your problem on the net, you may find someone who found a solution to your problem, if not I'm sure Amazon has customer care.
