Broni, I already tried this, as JJ 3000 suggested, without success, but I guess, since I've tried other stuff since, you think it might hopefully work this time. It didn't. Then again, maybe it did, to some extent.
Before I posted this problem, I tried to open Help and Support every way I could, including Start > Search > Information in Help and Support Center, without success. Well I must have done something right, as now I can open it through the Search facility! Yeah for me! Should I tempt fate and try to fix this properly or should I just count my blessings?
