Hi there,
A couple months ago I bought the AI War Alien Bundle at Gamersgate along with what was at that time a pre-order for the Ancient Shadows expansion. I've been rather busy and I have a bit of a game backlog so only now getting around to installing and trying the game out, though it looks great so far.
The issue is that all of the serial numbers from the Alien Bundle activate on Steam, but the serial number I got with the Ancient Shadows expansion does not. Steam says it is invalid. I also do not see a way in-game to manually add the expansion. I could of course download the games directly from Gamersgate and install them outside of Steam, but I like to have my games organized in one place as much as possible and of course earn achievements which is usually not doable without some kind of platform like Steam.
Anyway, my question is, is this a bug or is this how it was meant to work (i.e. the Gamersgate version of Ancient Shadows never was meant to be Steam compatible for some reason)? And if it is a bug, is there any way to resolve it please?
Thank you very much.
