I just downloaded the latest build and my problem is still happening. Whenever I open the AH I get an error message (below). I also get an error message when I click on an item for the first time after the game loads. Dono why.

Oh, and I agree with someone else who mentioned the compactUI is too small. I like it better when it's compact like that, and the color coded percent is awesome, it's just difficult to tell what goes with what in the middle. The prices are so far away from the names (and close together). Doesn't the background color alternate slightly for each row? Maybe you can make that alternating background color more distinct.

Anyways, the error message I get in case it helps. Reads like Greek to me.

I was not aware such a FAQ existed, sorry. Also, when I started trying AA I just copied in the files and removed the old auctioneer folder. I didn't realize there was another folder I had to remove...
