Two "rented" ebooks have accidentally been deleted, and when I try to download them again it says "Error getting License. License Server Communication Problem: E_ADEPT_DUPLICATE_TRANSACTION_ID". How do I get them back?? They're textbooks and I need them to do my homework.
you can look for your book in mentioned folder,
C:\Users\<username>\Documents\My Digital Editions\
Hope this works !!
