Hello I have a problem with my Laseraxe DIY Desktop Mini Laser Engraver Engraving Machine Laser Cutter 7000mw. Yesterday I worked with full power but today almost no laser strength more .... Can anyone help me with that??

Where can I get a version of the cnc software that came with my machines a couple years ago? I lost the disc during a move and got a new computer so I need to reinstall my software. I prefer the older version if possible
