Crashing!

[gocarter]

I have been running UCCNC version 1.2111 with a uc100 on a Lenovo laptop (i5, 16 Gb Ram, Win 10 pro) for about 14 months problem free. A Week ago, UCCNC started closing mid program run. No error. messages, program closes and I see the desktop. I have not made any changes to my set up that I am a aware of other than windows 10 updates. I updated my uccnc software to the latest version on the web site, and it ran for a few hours and then crashed on me as well.(no error messages, program just closes and machine freezes, and I get my desktop screen.)
I only use this computer for uccnc.

Any ideas?

I had similar issues using AXBB. I spent a few weeks chasing it down, updating everything , problem still persisted. I finally tracked it down to my incoming garage service cable. I lost the ground leg and it caused all kinds of erratic behavior. Its easy to check with an GFI outlet checker.
