Thanks for contributing to our forum. Based on what you described, it sounds like you are most likely unable to generate an eBay token for the new Auctiva account you created because your eBay account is already linked to the other Auctiva account you had used in the past.
Assuming that is the case, the best solution may be to close the new account you have created and continue using your existing account, but it is also possible that it will make more sense to simply remove the token from the old account.
In order to receive assistance with this issue, please contact our Customer Support team by mousing over the “Help” tab within your account and selecting the “File Support Case” option. Be sure to include your eBay username in the details you provide as well.
