Thanks Tullik. I am on a business trip, but will follow your suggestions to see if it helps.
I do have a restore point from before SP1 installation. I was reluctant to restore to this point while running SP1. I tried to uninstall SP1, but that failed. Basically, I was trying to go "backwards" in sequence to get myself to a point approx. matching the restore point (if that makes sense).
I will certainly list any fix that works or my findings, as others may face a similar issue.
Thanks again for help anyone has/would provide...much appreciated.
