Moving this discussion to the Captivate Getting Started forum.
Laurat40589147 if you are facing difficulties with your Captivate membership then I would recommend contacting our support team directly at Contact Customer Care.
I was having the same problem and my IT person said to log OUT of the Adobe Creative Cloud and then try Captivate. It worked for me. Now if I ever get that message, I shut down Captivate, log out of the Creative Cloud, then launch Captivate again. I get prompted for my Adobe ID and password, and then I'm in.
Hope this helps.
