No Music Folders Found. Please Change The Settings

I just installed Subsonic on my XP machine. The install went fine and the server is running. I cannot get it to work on my local machine.
I connect through the http://localhost address and log in as admin. I tried to set the music folder to the directory where my music is stored (F:\Alt.Documents\Alt.Music\Music) but It tells me No Music Folders Found.
I am the sole user of this machine and I have full admin rights. What am I doing wrong? Can someone please help? I'd really like to get it working.
Thanks!
