Help with grises50 please

Hi,Have surfed along numerous threads and sites in de hope to find a solution. For exemple: grises50 needs the resample.exe from Terrain SDK FS2002 (= less buggy than the other versions they say). I found a link... but still no success. It seems I need the right version and I have tried them all.Maybe someone can send me the right software in total so that I can see if that works also for me. Can someone explain the .raw file thing (is the use of Paint Shop Pro 7 enough or must it be a recent version.... and what about the .inf file ?). Many questions.Anny suggestions ?Greetz. Jos
