So what does it do, and what does the score read now?
Have you tried manually setting the score to 0 and see if the game starts? if so, set all the reels to 1 and see if any reset. not familiar with the game, but if there is anything like bonus or hit targets or anything else on the playfield that has a 0 or reset position try setting those to the position they would be at the start of a game.
