Fireconteol 21.1 issues?

I downloaded the update and all day I am fighting glitchy issues. Program stops moving after a cut and then just burns until I turn off the power. I Uninstaller everything and got a fresh download. I was able to cut a few pieces after that. However the machine kept moving the zeros position. When I try to restart the program it would be off about 2 inches 1 time and 3 inches another.
