Have you downloaded the patch? If not try that. If it still doesn't work delete the file and redownload, but next time wait till it's 100% before installing and playing,
The patch was installed before the main download even took place.
See, the reason I'm asking is because the whole download/install process is very weird with this game. It seems to have installed while it was downloading, which is an issue for me, because the electricity can power off at any time in this city.
