Hi Adrian
I am currently trying to solve this problem myself. I spent a considerable amount of time on the phone to eBay last night but to no avail. They promised to sort it out, but when I tried to list again this morning, it still wouldn't work. The main issue was that I am an unsited member(registered with eBay.com, but not living in the US), which is probably the reason you also struggled. Have you had any solutions as yet? I will let you know the outcome of my attempts today, if they are successful.
