E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER
Dear All
I have bought a biostatistics book from accp.com, downloaded ADE, authorized the device without AdobeID, downloaded the book (through .acsm link file) opened it, worked perfectly
then i tried to authorize the device using my AdobeID, the book did not open and i have received the following error message:
Error getting license
License server communication problem: E_LIC_ALREADY_FULFILLED_BY_ANOTHER_USER

I searched for the downloded book in the ADE folder tried to open it and got this mmessage

I will appreciate if any one can help me in this issue, thanks
