Anyone still have any ideas why this Mac won't open applications? After a complete reformat and reinstall of OS 9.2.2, it still won't launch Stuffit Expander (type 3 error.. save work & restart) and it won't let me open some system files like "Late Breaking News.." aka Mac Help.

(Also, sometimes when it goes to shut down.. it gives me a bomb error "Finder".. error type 7?

I appreciate any help!
