Windows Update destroyed a PC TuneUp installation

After Windows Update today, an installation of PC TuneUp we have turned into a Trial version.

I made the mistake of buying a new subscription to AVG Ultimate. Our current AVG Ultimate subscription expires in October; however, we don't need the new AVG Ultimate subscription.

1.) Can we get a refund for the pointless AVG Ultimate subscription we just bought?
2.) How can my installation of PC TuneUp be restored to its non-trial version status?
I already installed PC TuneUp over my previous version.
AVG TuneUp on one computer is working fine.
