I have not used bid slammer recently and I am getting and error that my account isn’t found. Help.

Hello,
Try to run through the Sign Up process on our home page. This will refresh your authorization, but it will not create a new account. As long as you are still using the same eBay Userid, and it appears that you are.
Please let us know if this does not resolve the issue, and we can take the next step.
Good luck sniping!
