I did the restore point. There was only one, and it was 6 days ago. I was afraid of what I might lose when the computer went back to an older state, but as I read through, it assured me I would not lose documents. It worked beautifully. Now everything seems to work right.
I WISH I COULD uninstall 2007, but it is corrupted and WILL NOT uninstall. I'd like to know where the exact files are and the exact registry entries, so I could yank it out by the roots and never have this happen again.
Thankfully, now I don't need to re-install Office XP (It shows as 2002, not XP, in the Help About). When I bought this computer with Win 7, I installed several important software packages I carried from machine to machine (as they each died in turn). Unfortunately, I had all those CDs in a box and a certain neat-freak who shall remain nameless threw them away. So anything I lose now is forever gone.
I may need to download Open Office as a back-up plan.
