Registration invalid. in Galactic Civilizations I Stardock Forums

As my copy of Galactic Civilizations was the Ultimate Edition, it came with Altarian Prophecy exspansion on the disk. As the disk has one registration code what do I put in the Altarian Prophecy Serial Number slot? I used the same code as GC, being the same disk, but it says I can not update as the code is invalid. Any ideas?
