Hello I am new to this forum today, live in the UK, and have had my kindle since Christmas I recently gifted my sister one, and as I had used Calibre for conversion and transfer to my Kindle, without problems, I advised her to use this. I should add at this point we are both Senior Citizens. Unfortunately my sister has registered with Calibre using her e.mail address and not the Kindle e.mail address, consequently the books are not being sent to the Kindle. She has uninstalled the programme and re installed but cannot change the e.mail address. I wonder if anyone has a solution to this problem please
