Hey np yw, I havent really started using stardock software until recently as well. If you goto tools then settings then change the dropdown box from my games to sins , I think thats where you put the serial number in, click a button then it activates then all you have to do is create an ICO account from within the game and you are good to go

Im glad you have it all sorted out, either way if you have any hassle SD are good at sorting stuff out. I actually bought gciv 2 a while ago and because I backed up the invoice and other info they were able to merge my 2 accounts to one account and they did it under 24 hours. Pretty dam helpful!
