Hi. New to this forum. I have a 50 W fiber laser engraver from China. It came with a flash drive with EZCAD software. When I open the software, I get "cannot find dongle" message. I have tried uninstalling and reinstalling software, still cannot get the laser to work. I have gotten no response from the seller when I have enquired about it. Any help would be appreciated!
The EZCAD is version 2.14.11
