My books won't open suddenly
Although my books used to open OK, they now refuse to do so and report 'unknown permission error'. I think the problem may be that I changed the password on my account, and also changed it on my Adobe ID account, but I can't change it on in the Digeital editions. Since one of the books was hugely expensive and I need it urgently, I don't want to risk losing it altogether! I am thinking of erasing authorisation and re-authorising it with the new password, but will this mean losing the books as well. Has anyone any ideas, please? Is it even possible to change the authorisation?
Thank you
