Have you earlier activated ADE using Anonymous account? If, yes, you might have fulfilled the books using that account.

More info on Anonymous activation, Adobe Digital Editions – Anonymous Activation .

‌hi and thank you for your reply.  i only have 1 account. would my username be different to my ID?

This error message will appear if the same book had been downloaded using different account. That is the reason I think, you might have activated ADE earlier by choosing the option Activate without an ID.
