How do I modify or delete my ID, email address, etc. and start anew?

[fmar26]

I followed the instructions in the FAQ, but I still cannot open 2 books that I bought on my laptop and copied on my tablet. I would like to change my email address and My ID on bothe my Laptop and my computer. The ID on my laptop and tablet are not the same as I could not remember my ID of the laptop when I registered on my tablet. The message when I try to open the book on my tablet is "the book belongs to another person"

Thank you for your help.

You can get your ID information by by pressing Ctrl+Shift+I or by selecting the menu item Help --> Authorization Information...

Hope this helps.
