Just a thought, but you may want to make sure that the "Help and Support"
service started up properly.
To check k it out, go to Start/Control Panel/Administrative Tools/Services.
Then, scroll down to "Help and Support" and double-click.
Change the Startup Type drop-down window selection to "Automatic", and the
Service Status to "Start" (or "Resume"), and click OK.
Check the Status/Startup Type on the Service Page (it should now read as
Started/Automatic, and then try accessing the Help Center again.
Let us know if this works. Good Luck!
