I have had my router for ten years and for the most part works fine. I had to reload mach3 with my disk. It will load, refhome,jog but will not load the g-codes I have installed it on 4 computers and it does the same thing. I have been on support with my machine teck and he is lost also, it seems to be a software problem to me. Can anyone help?

What happens when you try to load the g-code?

I see a massage, but it goes by so fast I can't read then nothing no codes.
