I go through the authorization process fine - over and over again - but whenever I click "agree" button to relink Bidslammer and Ebay I land on "Page not Found." How do I resolve this

Hello Christine,
Thank you for your question about the authorization. I'll check into this and get back to you ASAP.
May I ask the reason for the auth? This will help -- to know if it was one of 3 things,
1) Just to renew
2) It expired
3) You received an email from us about invalidation.
Your response will help, I will watch for your reply.
