Free trial expired immediately after running driver updater!

I subscribed to the 14-day free trial for CCleaner Pro, ran the driver updater, was asked to restart the computer, and as soon as I did that, was informed that my free trial had expired. Poof! It was gone, as if by magic!

All of that happened within the space of a few minutes.

How could that have happened and how can my free trial be restored?

the only explanation for it is that you had already installed the trial version, before, and that the trial period had expired.
