Help with Napster, Vista, Replay Music

I downloaded the trial version of Replay Music so that I could see if it works with my Napster account before buying a copy. I can't get it to work.

PROBLEM 1:
When I record something it looks like it is recording, but once the song is done the recording time goes from 4:03 (example) to 0:00 and the song will not play.

I tried recording just 1:30 of a song and it did work. But when I try to record the whole song, it looks like it is recording because the recording bar is moving around and the time is accumulating. But once I stop the recording the time goes away and the song will not play.

PROBLEM 2:
The software doesn't know who the artist or song is.

SETTINGS AND SYSTEM INFO:
I have Vista and IE8
I'm using the web based version of Napster
I have the plug in installed on Windows Media Player
I removed the user security per the Applian instructions for Vista (Is this really required?)
I have set Replay Music to use the sound card
I launch Replay Music and press "record" before opening IE8

Help?

If I can't get Replay Music to work, what should I try?

Thanks,

Bill
