This should work. I got CM installed on 3 different computers with the same license and have no problems at all. As long as you don`t have all 10 (I am not quite sure about this number) activations used. If this is allowed by License Agreements by Battlefront or not I don`t know. But where is no complainant there is no judge...
This is all located over there at Battlefront if you are logged in under My Account. If your downloads have already expired (I don`t know if this could be still the case) we will find a way via Dropbox or somefink.
I only have CMBN and all modules installed on one computer. I am trying to install this a second time on the same computer but on a different HDD. I want an earlier version on the game. But when I try to run it it is telling me all my activations are used up. Entered a help desk ticket on this.
