Auto-organize putting music in Unknown artist folder

[xandora]

For the life of me I can't figure out why MediaMonkey is putting my music into an Unknown folder. All the music that is in the library has been in this library and has been tagged correctly before, but recently I reinstalled Windows 7 and now only some of my music is organised correctly into appropriate artist folders.

Here's a gallery of the settings I have set at the moment.

As you can see, the files are all tagged correctly, but not in the same folder.

You're using <Album Artist> which likely is empty/unknown which is why you're seeing this result.

Ahhh... I see. I knew it had to be something simple like that. It's working perfectly now.

Thanks.
