Is your system totally up to date including all browsers and their add-ons? Also check your system clock for accuracy.
Probably your best approach to this would be to uninstall everything via Control Panel > Programs.
Then run the MCPR cleanup tool and reboot.
Go to your online account page and reinstall from there.
If the problem continues after that, then contact Technical Support. It's free by phone or online chat and linked under Useful Links at the top of this page.
That seems to have worked perfectly. Thank you so much. : )
Glad to help. Sometimes when software upgrades there are problems and this usually works.
