This problem appears to have no answer just suggestions that I use a different browser or contact the publisher. Are there more suggestions?
Window 10 user. The e-book works on my laptop but not my desktop. Same error. I have tried Chrome, IE and Firefox. I have two files for the same book (the old from 2014) indicated E_ADEPT_REQUEST_EXPIRED, and the new just receive from the publisher indicates that Error getting License, License Server Communication Problem, E_ADEPT_REQUEST_ NO_TOKEN error.
I have been working on this problem for several weeks and cannot find a solution, help is appreciated.
Has you ask the publisher for check the file?
