unable to build...

[Terminator]

Once on Alpha centauri, I am unable to build colonists. In addition, I have not been able to build Capitalism on Earth or AC. Any advice?? Does pollution on AC affect Earth??

(1) In order to build colonists, you need to research Ultrastring Theory. You must also reach AC by 2020...If you have done all the above, and still cannot research Ultrastring Theory, download the 1.1 patch, but be advised it will not work with your current saved games.

(2) Capitalism isn't something you build...it allows you to convert your rescource shields into gold.
