The problem is that in my case the game not even starts in reality. After clicking the application the only thing that appears in the screen is a box saying
The application SimCity 4 rush hour quit enexpectedly.
Mac OSX and other applications are not affected.
Click Relaunch to launch the application again. Click to Report to see more details or send a report to Apple.
The only different thing I did before the game crashed was:
I lowered the graphic resolution to make a test, I wanted to know if my comp would run better. After this I restored settings to default to compare graphics and the game never worked again. I already downloaded the game twice and tried to run hundreds of times but with no success.
Any help?
