Thanks, bagginsbill, for those links.  Tried all the tips I read there, but so far nothing has worked.  I uninstalled McAfee (came with the computer) or rather I think I did.  Halfway through the uninstall it kicked me offline and then the uninstall froze and wouldn't move so finally I just shut down the computer.  When I restarted McAfee was no longer in the 'Uninstall' list but probably lurking somewhere.  I downloaded and installed SP1 for Pro, but that did nothing either.  Reinstalled Pro again with no luck.  Last ditch effort is to try a system restore, which I really don't want to do.  I suspect that will put McAfee back on my computer.  argh!!!!!!!  Sometimes I hate technology.
