I purchased a textbook a while back and I was able to open it on digital editions and had been using it fine. Then I quit the program and tried to reopen it today to read some more and when I tried to access the ebook, it wouldn't let me. I tried to reopen it from the publisher's link and it just reads:
Error getting license
License server communication problem: E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER
I don't know what to do. I need to have access to my textbook.
