It's a moronic issue......
Go into the zone categories and change them all to a zone currently loaded in your library (hint: it will have a name that includes the current version of AC, Zone identifier 12 for AC 12).
The bigger question:
Why the hell are you NOT using zones?
This, my kind lec, is something to reconsider.
