Lightburn suddenly not working

Hello guys, I have been using Lightburn for over a year with little to no problems, but today I encountered a problem which doesn’t seem to go away, when I load a project and start, the laser head does not move at all and just fires on one place, I have not tinkered with settings at all, I have tried uninstalling and reinstalling the software to no solution. I am losing my head. Please help. I have attached my code from the console tab, hopefully this will help.

Waiting for connection…

Reset while in motion. Grbl cannot guarantee position. Lost steps are likely. Re-homing is highly recommended.

Using a Sculpfun S9, auto Homing is disabled.

Can you see anything in the preview window? I had this problem once and noticed that the preview window did not show anything. I had to reset the layers to default values, that cleared up the issue.

If you send movement commands via the move window (arrow buttons) does the laser move? Do you get any feedback in the console window?
