Checking
OK there is a "MogProgWF.exe" 7-zip in your folder which makes a work folder.
The missing file "PlaneCodes.txt" is in it.
I added "lane" as the last entry in "PlaneCodes.txt" so that it can convert to 140 format if you ever need to
If you only downloaded the "MogProg2016 V3.exe" it is not a 7-zip, but a newer exe that converts PCX files also. It was meant to be put in the work folder
