My eBook device constantly throws E_ADEPT_CORE_USER_NOT_ACTIVATED, but my Adobe ID is registered with the device, how do I fix this problem?

I tried to get this problem fixed over at chat but they weren't at all helpful.

The problem is I have a Tolino Shine, and for whatever reason when I connected it to my Surface Pro 3 so that it would charge the Adobe DRM authorization was lost. So when I went to reactivate it in the book I realized I had forgotten the password. So I went to the Adobe website and requested a password change, and changed it. I then went back to my Tolino and activated the Adobe ID there and all seemed good, until I tried to read a book. It tells me that the Adobe DRM is not activated and throws the E_ADEPT_CORE_USER_NOT_ACTIVATED error.

How can I fix this problem?

Try to set his Reader to default Settings and then try to authorize again.

Hi Jason,

This error is seen while trying to open a book that is authorized for a user different than the user currently logged in.

To correct this error, please try to log in with the Adobe ID with which the content was fulfilled.

It's possible that some of the books were copied onto my device by my sister-in-law, but they were readable then, what would cause them to become unreadable now?

It would most likely be that they were authorized with a different Adobe ID earlier or they were authorized using an Adobe ID which has been joined with another Vendor ID/Adobe ID.
