SimCity 4

[turbine2_de]

I have installed Sim City 4 and wanted to start it with the result that the loading sign on my mouse-dart was shown and the CD (original) has been read. But after the loading sign disappeared the CD was read a while longer. That is all. Nothing happended anymore that means the game doesn't start.
I have installed the game eith orig. cds and started the game with the orig. exe and the orig. cds.
What can I do? All needs of the game are fulfilled (EZ started).
Thanks for help
