FS 2002 Aircraft Editor

Hi, folks
Perhaps someone can help me figure out what happened to FS2002 Aircraft Editor. When I try using it I get an error message about a problem with fsedit.exe. It says: "fsedit.exe has ancountered a problem and needs to close." I do recall getting some sort of indication of a problem with fsedit.exe when I was logging off a couple of days ago. The bottom line is I can't use the Aircraft Editor. By the way, it's not necessary to use it when downloading aircraft, right? The downloads appear in FS2002 after I put them into the aircraft folder of 2002. What is the Aircraft Editor actually used for, then? Thanks.
