Hey anyone knows how i can download older version?
Judging by your other reply, I'm guessing you want an old version of the game to see if you no longer get any errors... But, to reiterate what Bladerune9 wrote to you:
just start anew and create new save files--on the basis that you can't reuse old ones with more recent versions of the game. (Pretty standard practice with many games, not just FC!)
