I just purchased GalCivII Ultimate Edition and Sins Of A Solar Empire from amazon.co.uk
they have both installed fine, but only SOAE has registered correctly. the serial provided for GC2 comes up as invalid, it then offers me a download of GalCiv2 Endless Universe, and on the registrations page it shows this product with the same serial number as Ultimate Edition, and says that its valid.
so it appears i've been given the serial number for the wrong product. what can i do about this? i definitely have the box, disc and manual for Ultimate Edition.
