I just purchased the expansions on Impulse, and downloaded them, but I recieved activation errors in the form of a text document each time I did so. I am able to play the game, but does this mean that I will not be able to update the games? I did buy the games under a seperate e-mail address than my username is linked to (Which has caused problems with me before, but I did it again because I was in a hurry and forgot.)
