I've been having this problem for 2 days now as well.

Great. I've been evaluating AW2K for 4 weeks now, and was ready to buy it today before the March 1 cutoff. It would appear now that it is worthless to me until somebody gets off their keister and fixes the conflict with eBay's new requirements.

Does this problem indicate that every time eBay changes anything in their listing routines, AW2K users will be SOL, unable to list anything at all for several days?
