'Century Guitars' instrument showing as complete in 'Install your content list' in shop, but nothing showing in program instrument list at all. All other instruments installed ok.
Try this. Go to the Program Settings, General Settings, and press on the Cleanup Store button. When Music Maker restarts, you will have to log in again. Then check. If Century Guitars doesn't show up under instruments, check under Downloads and if there, try downloading and installing it again.
