Paul,
No changes on my PC laptop Windows 10 since I successfully used PM 6.0.0.3954 yesterday.
Repeated clicking on icon gave me nothing but on one occasion.... "One of PM6 subsystems failed to initialize. This may indicate an installation issue. DYN_WINDOW_EXCEPTION"
For a problem like this, I suggest contacting our support folks at:
By email: support@camerabits.com
By phone: +1 503.547.2800 option 2
Hours: Mon-Fri, 9:00am-5:00pm [PST/PDT]
