I have an old retail version of Far Cry 1 and would like to register it on Uplay. I want it added to my game library so I dont have to install from 5 CDs anymore. I tried "Activating a key" under the Uplay menus and it didnt work, then I tried putting the game in my cart and putting the CD key in as a Promotional code and that didnt work either.

Is there any way to add it to my Uplay library?
