So is this supposed to work with an old 'disk' based installation (meaning you dont have to rebuy the main game or some lesser game re-install) ?

I never really cared to use my real credit card to buy it (dont use it for ANYTHING online) and a number of 'gift' cards repeatedly failed (apparently the lame  interface required a 'name' and barfed if you had none).
