Hi Cousin Vinny,
Since the link to your "About Me" page is producing the aforementioned error message, it is indicative that your eBay username is not coded into the link properly. I believe this problem can be corrected by replacing the incorrect username in the link HTML with your current eBay username.
If you are uncertain how to accomplish this, and you would like further assistance, please file a support request using the appropriate link on our help page: http://www.auctiva.com/free-auction-software-help/help.aspx
