Hello,
I asked HELP to advise me (the reply was almost immediate) and was told I needed to regenerate my Ebay token. They gave me a url to go to >>>> <ahref="../ebayutil/tokencreate.aspx">Get Token</a>
but it was not the correct URL and I got an error message. So - I went to my auctiva account and just clicked on Ebay Settings and clicked on "Generate A New Ebay Token" and now all is working again for me. Strange thing is that my Ebay token had not even expired so I don't get that part.
