I have an early G4 running OSX tiger. I have classic software that needs OS 9 to run but classic will not start up, there seems to be an issue, I get an error about quicktime, then it looks like Classic is going to start then nothing. Can I reload and do updates to OS 9 while OSX is loaded?

One other thing, I only had ver 9.1 loaded when I installed Tiger 9.2 update just wouldn't take for some reason.
