I have smart pro. All my ray widgets are changing from registered to "not registered" and stop to work as soon I go to admin area of ray. The reason could be that admin area of ray is writing wrong entries to main.xml files in ray widget modules so they change to "not registered" during license checking procedure.
Trying to do new registration does not work. To get ray widgets to work I editet main.xml files in ray widgets and changed the entry "not registered" to "enabled". It works as a short time solution only because as soon you go to the admin area of ray, entries in main.xml changing to "not registered" again.
I am waiting for a bug fix from boonex. Maybe mailfunction in license checking procedures.
