Problem with Replay music and Napster: all songs come with unrecognized tag

Recently running Replay Music with Napster, it is going out to Gracenote to try and tag, but all music is coming back with tag of "unrecognized". Is there something that changed in recent Replay music? I think I am running 3.0.

Secondly, now that I have recorded a few handful of songs, is there a way to run Reply music again to have it simply go tag existing "unrecognized" titles with out re-recording all the files? Or, does gracenote have a routine or application that will run through a folder and tag everything?

Thanks
