Although I need to get back online yesterday, I'm reluctant to do a clean reinstall because last time I did one, I couldn't reinstall my Microsoft Office 2003 even with the disk. I don't recall the error message I got but I ended up having to take my computer to my tech person so he could use his Office disk.
So I guess what I'm saying is I really don't know what to do other than start looking for a new computer in the morning.
