I've just downloaded the STO client, but it seems like I need an activation/product key. Do I get this once I've purchased a subscription, or do I also have to pay for the client as a digital download/physical dvd? Just that I thought this was like most MMO's - download the client free, but purchase a subscription to play... I would have asked this in the STO forums, but I don't have permission to post, despite having made an account...
