I have been pretty good but this time I was not - serial #

Was there a serial # for ROP-Gold- upgrade kit? I have the order receipt (and a serial # for the full game from my initial purchase).

I wanted to see if I could register it on Steam and realized I cannot find the serial # for the Gold upgrade kit.

Did it have one?

I'm very curious about this as well. I'm pretty sure I had the original ROP from GamersGate (there's a paradox logo on the box cover too), and then got the upgrade from AGEod...found the emailed invoice and there was no serial #.

I remember why I didn't register it here. I registered at Paradox.
