I just bought Sins of a solar empire + Entrenchment and I received an email telling me so. Under Entrenchment I received a serial number, so I registered the game. However under Sins of a Solar Empire I did not receive a serial number in the email. I asked Stardock to give me all my serial numbers and still, it says I have Sins of a Solar Empire, but it has no serial number. How do I get the serial number. Oh and of course I can't go to my games tab to find out because I haven't registered it yet because I don't have the serial number.
