This may be "dumb," but have you tried entering a THREE letter keyword in place of a FOUR? All the Fast Fox examples use three letters; maybe the prog wants to always see that? I dunno. Just a thought. Otherwise, as others mention, the 64-bit processor you have causes as many problems as "XP Emulation Mode," touted to let you run XP progs on Win 7, BUT, it is selective, and some will NOT run.
