Need to login to add books, but I'm already logged in

I clicked the add button to add a book, and it asks me to login or cancel, so I click login and it tells me I am logged in.

Same story clicking any add button. I can sync with the cloud, and everything else works.

Any thoughts?

I think we already resolved this by email.

We did, thanks.

The resolution was to change the account password and log in again.
