Hi sawyer62,
The reason you are receiving the aforementioned error in response to your token generation attempts is because your eBay account is already associated with an existing Auctiva account, and only one Auctiva account can be associated with each eBay account at any given time.
If you are still experiencing this problem, please contact our customer support department using the appropriate link on our help page, http://www.auctiva.com/free-auction-software-help/help.aspx, and we'll be happy to help.
