HI,

You have upgraded to the new API version. So that is good.
And from the sounds of it, you have not listed in a while using AW2K? Are you relisting or listing new Auctions? If you are relisting, try deleting the old Auction ID numbers from the Auction number field.

And have you checked your computer date and time to be sure it is accurate? AW2K is sensitive to date and time.
