Thank you for the response. This is what I was suspecting the problem was. That each civilization was only allowed one time. I have not created any custom races and I have not purchased, bought, downloaded the additional civilizations pack.
I believe you have resolved the issue and being that simple I assume most everyone else figured it out.
Next will be deciding if I want to create custom or get the pack.
Again thank you.
You will have to "create" more Civs, the Species Pack does not give new Civs just more options for creating Civs.
The SP gives new types of species you can build, one is a species of Clouds.
Stardock may in the future add more Civs they did in the other Versions however that has not been confirmed at this time.
