I did not realize when I listed it that e-frontier has a thing about such auctions. (I guess I don't read all these TOS and EULAs as carefully as I once did.)

I sent them an email explaining that I did not intend to cause any trouble. I have not heard anything back yet, but may tomorrow, er, later today.

Since e-frontier knows for a fact that it is not pirated and new (since they gave it to me), maybe they will make an exception for me. If not, i.e., if I have to cancel the auction, very sorry to any and all interested parties in advance.
