Digital editions is set-up and accepting books. Everything seems fine except when I try to open the books, it asks for authorisation. I enter the Adobe ID which works when I go into the Adobe site, but gives me the error "The vendor account you entered is not associated with the item you are trying to open. Please try again". How do I fix this?
Try this (it worked for me):
1) In ADEditions, go to Help --> Erase Authorization
2) In ADEditions, go to Help --> Authorize [using Adobe ID]
3) Select Book(s) --> right click --> Remove from Library
4) Re-add book(s) (in case that you have an .acsm file with a link, open this file with ADEditions)
