Rebooted in Safe Mode, jv16PT still not functioning.
Deleated and reinstalled jv16PT....had no problems. Worked as expected.
Rebooted; all other anti-this & anti-that programs still running (they start when Windows starts). Then, tried to use jv16PT.....WOW....same problem, jv16PT not fuctioning.
I reconfigured all my anti-whatever software so that none would automatically start (except for my firewall).
Uninstalled jv16PT, rebooted and reinstalled jv16PT.
NOW, finally, jv16PT works.

Found out that "real time" anti-whatever is not required....can do anti-???, manually.
