Sculptfun S9 error

I am getting the following error on my Win 10 machine. This is the latest version of Lightburn too. Any suggestions? Thanks in advance!

Lightburn transfer failed 1.5.01 “there was a problem sending data to the laser. The machine may be busy or paused.”

Have you tried restart on both unit and software?

Yes. No change. Laser was working fine till the small fire in my containment box. Replaced the cables, now I get this error.
