Unable to create your city at this time. Please claim a city again later

Just thought I would add my hat to this. I struggled to get the game to even start, I had the random crashing at start up, but having finally sorted that out and finished the tutorial, I can't start my own city. 

This really is starting to remind me of Diablo 3 all over again. Game gets released and it's a week or two before I can even start playing the game decently. 

Not impressed so far...
