Hi, I keep getting an invalid token verification error everytime i try to use it. I already keep signing on but it keeps bringing me back to the invalid token page.

Hello Said,
Thank you for your question about authorization. You apparently changed your eBay ID and so you have two accounts with us. It is trying to update your old account. Are you still using the ID "sbahasua-0" ?
Please let us know and we can take the next step.
