I need some help, I installed mach 4 on an older xp PC. It installed fine, and starts. as soon as I try to load ANY g-code file it immediately force closes. I use the exact same setup on two other machines without trouble. I have tried everything I can think of. Clean install, service pack 3, latest MACH4, etc. It fails on mill and lathe profiles, mine and oem. The lathe functions, moves, can jog , etc... Thank you very much
