Trying to reset with Google Music

When Google music was first release from Beta I joined and uploaded my library. Despite the fact that my music library is meticulously tagged in iTunes many of the songs would show up on GM as simply a number or a number and track name with no other tag info or album art. I also noticed that anytime I edited tag data that those tracks were uploaded again to my GM library as duplicates.

Recently I decided to just delete my GM library and try re-uploading all of my music. This seemed simple enough, click on delete my library and wait the recommend several hours. Now my music is gone from Google, and it indicates 0 of 20,000 songs in settings. The problem is that despite having removed GM Manager and associated files and reinstalling, it still says that I have already uploaded 8,xxx of my 8,xxx song library and wond upload addition content.

Anyone have any insight into how to fix this problem? Been trying to find ways around the issue for a couple days, and haven't had any luck or help from the Google support staff.

UPDATE: In case anyone else runs into this issue. I have managed to resolve it by choosing the iTunes music folder manually instead of simply choosing iTunes in the Music Manager settings.
