How to tell if the version of SoundTap I downloaded and Registered is the Professional version

I underwent quite a lot of confusion and doubts trying to Pay for and Download the Professional version of sound Tap.

How can I tell for sure that the version I'm running is the "Professional" version?

After clicking the "SoundTap" menu button then the "Register Software" button and entering the reg code . . .

I saw ... "SoundTap by NCH software - Licensed Software" on the interface.

Neither of the help buttons on the interface mention the "Professional" version.

Is there some quick way to determine for sure, what version I'm running?

Click the Menu (top-left), then HELP | ABOUT. You're likely good either way...
