BrianTed,
Same thing happened to me about a year ago. The explanation was that I had not paid the fee to be allowed to bid in their big auctions, but was allowed to bid in their collector (is that right?) auction.
I paid the $75 or whatever and the problem was fixed.
And don't bid against me -- I will give you first crack at the card(s) I am upgrading
