I just registered my copy of Gal Civ II Ultimate with the Stardock Store, and it's not showing up. I can provide my serial number for the game on request.
Did you use this same email as the forum? I'm not seeing the registration. Are you using https://services.stardock.net/accounts/registerproduct.aspx
i like how your system is available to charge my bank account, but cant manage to make a digital download available when it does take my money. great service here. why should any of your customers wait multiple days for a download, that's the entire point of a digital download..... to no wait.
I see your purchase or Rebellion. Hit the first link above see what happens.
