I tried to install a recently purchased book I purchased from Libronix into my Logos 4.0. By this I mean I opened up my Logos 4.0 program to start it and then I put the newly purchased CD into my PC tray, thinking a screen would popup like "library management" ? Well to my disapoinment NOTHING showed, but I was able to install the new purchased CD into my old 3.0g program thankfully. Why am I unable to install new books from a CD into the Logos 4.0 program?
