I've recently got the munchies for some D2 LoD action again and. I used Serbys cd key changer on the copies folder and put in my key I received from the . Ok so I purchased two copies of d2 and expansion. Ok so I am trying to run 2 diablos on 1 account and am having issues with the program that lets you do that. Simply type in the key you already have, and the game should be added to your account. 2 min - Uploaded by SnyltTo start get here is the link to PorjectEtals wiki about the subject. pretty sure the easiest way is to install the game once then move all the files to a new location then install again with your other key. Only thing is I can't find a proper link for serbys CD changer.
