I have successfully downloaded and transferred books to my e reader from my computer in the past, however I just downloaded a book to my computer and cannot transfer it to my e reader now. I am receiving the message "Error getting License. License Server communication problem E_ACT_NOT_READY " It says my computer is authorized so that is not the solution. I followed your help tips and attempted to erase computer authorization so that I could trash the activation.dat but Here I get the message "unable to erase authorization please try after some time." appears . Please help!!!
