I recently bought Sim City 3000, in a value pack from Maxis. All the other games work except for this one. when I put the disc in, the install menu comes up. I click install and a box comes up saying "C:\WINDOWS\SYSTEM32\AUTOEXEC.NT. The system file is not suitable for running MS-DOS and Microsoft Windows applications. Choose 'close' to terminate tha application." What do i do? please help!
