Idk why there isn't a section for GalCiz 2, it says RIGHT IN THE GAME FILES that stardock is involved.

I downloaded the "Ultimate Edition" from steam, and it turned out to be one of the worst game failures I've ever seen

Like it says, many problems with many many many many many many many many people, can't find any good solutions, idk why this isn't fixed yet. I try and install it from steam, and I just get errors that say to re-install and furthermore the CD key steam gave me is deemed invalid by the game installation process. I can't even access stardock info. I veried the integrity of the game cache, tried installing stuff from the main files in C:/Program Files/Steam, re-installed everything twice, and nothing, utter waste of money so far.

Is there ANYTHING that can fix anything about this problem?
