I just downloaded and installed the 1.1 patch, after reinstalling GalCiv 2.

When I run the game, I get a window pop up for Stardock Product activation. I enter the email address I registered with, and the Serial Number that Stardock sent to me at that email address.

However, when I press 'Activate', I get a message saying 'Invalid Registration'.

I just want to play, but it seems the patch has disabled my game somehow.

Any assistance in resolving this problem would be gratefully received.

Edit - I live in the UK and bought the UK Collector's Edition. This had no activation key with it, only the key for the collector's edition content. I used the service at http://galciv2.com/paradox/ to obtain a key. However, when I use this key to try and activate the game after applying the update, the key is rejected as being invalid. Please help!
