RC,
Excellent news for you, LCam is now working/saving for me. I completely uninstalled Mach 3 from my system this time(not my machining system) and reinstalled everything again.
I'm again using v3.00.2 and it is actually saving now. What's VERY interesting is that my older files WERE saved but wouldn't show up as saved. The whole thing is very odd but it's definitely working now.
It's worth a shot!
