I couldn't see how to sign out and sign in different. That was the problem. So I downloaded another version of kindle and logged into that and all went well. I have 292 books, it seems.
I one by one downloaded them all except for 20 which are registered to too many devices.
So I managed to find the devices page and I deregistered some from five years ago.
No I can't find that black page again which lists all your books and from which you can download them.
Sorry to be so inept. Could you tell me where it is?
I find it very confusing the way it jumps from Kindle to Amazon and account to account..
hmmm... I think I'm looking for a kindle page aren't I? On amazon screens. And won't find it. I think it drops to Amazon sometimes from Kindle, when you do certain things, and then you can't get back. Would that be right?
aaahhh.... delete all mention.... I just found the 'black' kindle page still open behind my browser entirely.....
thanks for your help. i might be okay now....
p.s. except deregistering devices doesn't seem to have worked. Perhaps it needs time to go through the system? Or I should shut down and restart the Kindle? There seems to no place within it where I can trouble shoot this 'too many devices' thing for a particular book.
