Just this week I installed this game on my new PC (running Windows 8.1). I'm trying to create a 2nd city in Single Player mode, and for some reason any SECOND city I click on just sits at the load screen saying "Now Entering: [ no city name]" and just hangs there spitting out tips but never loads, I have to ctrl+alt+del to get out of the game. It lets me play the first city I created when I started the region without issues, but I can't get any region to accept and load a 2nd city. I have searched on Google and can't find any other mention of this issue?? It is labeling all other cities in the region as "claimed" by me, even though I haven't yet "claimed" or played them, if that has anything to do with it...
