Cleanup Premium stopped working - reinstalled from trial version, fix subscripti

Avast Cleanup

When trying to run Cleanup Premium I got a message saying it couldn’t run, I presume the link from the shortcut to the program was broken.
Checking the FAQ, it suggested to re-install the program.

Found the email with the trial software link so re-installed the program successfully and it now runs successfully.

I did purchase the program when it was offered at a competitive price after the trial period earlier in the year, how do I ensure my new installation and my subscription dates are relinked successfully again so that everything is correct?

Subsequently found my actual order when I purchased the program and re-installed the program again.
Seemed to install exactly the same version so I’m hoping now that the program, which is working, and the subscription date are now back in sync.
