Hi jean8436,
While you may have revoked your eBay token associated with your previous Auctiva account through eBay, since you are receiving that error when you try to generate a token from your new account, it is indicative that your eBay account is still linked to your previous Auctiva account in our database.
We maintain these associations in our database to prevent sellers from using a new Auctiva account who already have an existing one in our system. If the scrolling gallery in your listings is associated with your previous Auctiva account and you were to switch to a new one, your scrolling galleries would soon be empty because the Auctiva account they are associated with would no longer have a token linking it to your eBay account.
If you contact our customer support team by completing the web form on the following page of our site, we'll be able to get this situation straightened out for you:
