John,
Yes, I have followed the instructions to the letter, this is not the first time putting this mod in, but this go round, each time I get the same error message after applying the mod. I get the message on the H.sie Options Selector when I press Stiebler Mods button.
I have even down loaded a new copy of Stiebler's mod thinking I had a corrupt file, getting the same result. After several tries, keep getting the same result. ( Is that not the definition of insanity, doing the same thing over and over and getting the same result ).

Good hunting,
