I get the same errors. I have chalked it up to changes in KGFF since this method used to work with KT. Since there have not been any updates to KT in nearly 2+ years and since then Tk102 has improved and fixed different things within his utilities this would lead me to believe that KT is looking for more than a file named "GFFEditor.exe" odds are it is also looking for some other internal hooks that have changed within the KGFF's program code.
Working so, we will learn history as a tree knows it; we will climb into shapes printed in the seed; we will become time made visible, years made fragrant; we will make of concentric memory a stem of praise; we will inhabit daylight at a trees own speed; we will be travelers who remain, patriots to this ground.
