geov This sounds like a combination of bug and update error. If you could see your albums and tracks after the update you _must_ have had a V10 database (with most likely incorrect scanned data) before. To check whether there is a bug when reorganizing the DB not updating the "faulty" data please follow these steps:
1. Close MP
2. Delete \Database\MusicDatabaseV10.db3
3. Open Config
4. Make sure all shares are configured
5. Tick every share
6. Uncheck the option to omit files scanned before a certain date
7. Update (recreate) your database from selected shares
8. Close Config
9. Post Configuration.log to http://pastebin-team-mediaportal.com
EDIT: Oh. seems like I was too slow answering...
