I have 0 out of 10 active auctions.

When I go to sell an item, it tells me something about how I can only have 0 items in my auction (or shared stash) and that I need to first move the item into my shared stash before selling it. I'd be more exact except I can't... log in (error 37).

I get the very same message when I try to buy an item from the auction house.

P.S. Make auctions 24 hours.
