I purchased the GalCiv II: Ultimate Bundle Pack (Digital Download) straight from Stardock back in 2008, and I was trying to get access to the game again. I have serial keys and download links for Galactic Civilizations II: Dark Avatar, Dread Lords, and Twilight of the Arnor, but I do not have a key or link for Galactic Civilizations II: Ultimate Edition. Using the Lookup Product Keys tool sends me everything in the bundle except for the Ultimate Edition.
Before I was able to get the game through Stardock Central, though now I find that is no longer used. I saw it was succeeded by Impulse (at Gamestop,) but that was also discontinued. I could register it on Steam if I had a serial key. How do I find the key?
