Dear Steve,
Thanks for letting us know about this. I reviewed your Auctiva account and found that your token generation attempts have failed because your eBay account is already linked to an existing Auctiva account. If you contact our customer support team about this, they will be able to provide you with a solution to this problem.
You can reach our customer support team by completing the web form on the following page of our site:
