I sent an e-mail and never got a response, so I though I'd address his on the forum:

I read about GalCiv2 ont he forums at paradoxplaza.com. Loved MOO & MOOII but never played many other space 4X games (sure I played MOO3, that 5X game to find out that the fifth X stood for "Xcrutiating"). Love the game but here's the question/problem:

I also want to run it on my laptop as my PC is not always available (like if I'm on the road or, for that matter, the couch). I can install it fine of course but when I install the update to 1.1 I get the error "The product appears to be validated but the serial number or the SID don't match."

Now right #2 of the license agreement says I can install it to my laptop (I am the primary user on both machines) and i would also like to update it to the latest version.

Any assistance would be appreciated - thank you.
