A question for an obscure game-making program

Okay, then. I have a question for people who use Sim RPG Maker 95(don't have it? There's google, but it mostly comes up with frenchie sites). I'm pretty sure that everyone has this error, but how do you fix it. When you try to testplay the game, you get as far as the main menu, but then it crashes and says you're missing a map data file 1,1. So, what's up with that? I've bugged around with it for a while, but I can't figure out what's wrong. Any helping?
