Hi Community,
Based on the behavior you have described, I suspect the reason you are unable to generate a token is because your eBay account is already associated with an existing Auctiva account other than the one you are currently attempting to generate a token for.
If you are still experiencing this problem and would like further assistance, please contact our customer support team by completing the web form on the following page of our site: http://www.auctiva.com/help/requesthelp.aspx
