Problem With Dongle, Gravograph


Recommended Posts

Hello everyone, I have a M40 machine since 2009, everything was ok until the day I enter some serials trying to stop the pop up window that shows up everytime I operate it.

 

Now when I try to open it, it shows up this message "The trial version has expired"

 

The dongle is damaged or blocked, What can I do to fix this?

 

Please Help Me out.
