I don't really think this is the answer - but it's worth checking ....

That repeat loop bothers me - if for some reason MyPathWay had no "/" 
characters, you'd be in an infinite loop ....
maybe add a safety check around it, or put its current value into a 
field to check ....
  if "/" is in MyPathWay then
    repeat until the last char of myPathWay is "/"
      delete last char of MyPathWay
    end repeat
 end if

or (what I'd do) ...
  set the itemDel to "/"
  delete the last item of MyPathWay
  -- and remember to set the itemDel back again, if necessary
  -- and remember that this strips the "" as well, so you'd then want to do
    put myPathWay & "/TJsettings.txt" into MyPathWay
