I'm using TunerCats OBD2 with Win 10.
What helps me prevent crashing is the way I open a .cal file.
I first load the .cal from a C drive location. (working from UBS Memory device is problematic)
After making sure the .cal is opened, I completely close the TunerCats OBD2 program.
I then Restart TunerCats OBD2 program.
I then select the same .cal file from the "File" drop down menu.
