Can not make a connection to "start" an engraving

I can not seem to get a Brand New Laser to work, When I pull it in to the USB Port I get an error: E.\ The directory is invalid., In the G Code Console I see that the laser is identified but when I “Start” and engrave it gives me this "error:20 Unsupported or invalid g-code command found in block. "

When I put in another drive into the same USB Plug it registers without error. I am thinking there is something wrong either with the cable or the USB plug on the laser? Any Ideas?
