opening sessions and pro tools closes immediately

[Jenk2k]

This problem began when i installed the standalone audio drivers for the 002. i followed the instructions to a T and it immediately caused major problems, including an error -6002, and "cannot initialize directIO"

Even after using norton ghost to restore my system I still get this problem.

I have alreayd used the tech support utility to delete prefs, etc. and already uninstalled and reinstalled PTLE 8.0.

I have a funny feeling that this is related to copying those dll files (all per the instructions) in the standalone information.

Any ideas on what I can do now that I've screwed up my system by copying all of these DLL's into my windows\system folder?
