I'm getting the 'couldn't decode items database information' error every time now. Abrosia's completely broken for me. I even tried uninstalling and reinstalling the whole program manager, and no change. It's weird, too, because the shop autopricer works fine...doesn't that also use the item database?
Don't know if this has anything to do with the problem but are you on a slow connection? I'm visiting home for the holidays and my family lives in the middle of a wheat field for some reason, so I'm on satellite internet atm.
