OK, I tried that, and my taskbar box still says I'm 'in danger' because my service has expired, but it shows as working on my IE menu bar, so I don't know what's up.
I tried at last to uninstall it, and FINALLY THEN it offers to reactivate for free, so I reactivated it that way, it "updated," and seems to be working (on IE anyway) while the taskbar still has it as a warning of expiration with a big red X on it saying it's not working...go figure.
I've about had it with this...that's the only thing I know for sure.
