I'm running Panther on an iBook G3 and recently ran Spring Cleaning to clean up the hard drive. I must have inadvertantly deleted a key system file as the computer starts up, takes me to the log-in screen and then returns the following error message when i attempt to enter my password: "Internal error TSM ProcessRewKeyCode failed (-192)" I've tried running disk repair from the original application disk, and it identified a problem and said it repaired it; however, the problem persists. I've tried re-installing OS X from the original application disk, but it won't let me re-install OS X over some newer components of the program that I have downloaded since the original installation. Any ideas or suggestions on how to solve this problem? Thanks.
IBook G3 Mac OS X (10.3.9)
