This sounds like a job for ... uber-Ficedula!
OK. LGP Tools isn't too complex so there's a limited number of things that can go wrong with it.
1) Make sure it's in a folder by itself, with NO other files in the folder (except possibly the Ficedula library code, if you haven't installed that in WindowsSystem).
2) Look for FICEDULA.INI (prob in Windows folder) and delete all the sections to do with LGP tools, should be obvious which ones are which.
3) Umm ... ok, I'm grasping here ... try another version of it & see if that works?
Actually, I'm just about to upload a new version of LGP Tools (possibly tonight?).
