When I start Mach3 I have to do a reset.  What pops up is the screen that says "fix this for me"  I always pushed it to fix it for me and then everything was fine.  but yesterday I hit the selection "don't show this again" at the lower left, thinking that Mach3 would always fix the problem for me.  BUT NOW IT WON'T!  How do I get the "fix it for me" screen to show up again???  I need it badly!

Sounds like your do not have an E-Stop switch on your machine, you really should
Anyway if you dont then go to config menu then Ports and Pins then Inputs and scroll down to E-Stop and change the active state to active Low.
If it is limit switch issues then changing the actove state of them will likely cure the problem.
