I would swap it, but A816 is not for sale here :S I'm not sure about the return... I'm not getting any error message, it just says that it failed transfering. Anyway, I tried to restore my PC to a state it was yesterday and reinstalled everything... and it works or looks like it works, so I hope the problem is gone. After 5 minutes: No, the problem is still there. It worked for two songs which I couldn't transfer before. It opens a window and says "Unable to transfer the track or tracks." and shows the tracks. The first in the folder
