Need a Save. Help!

[Greywyn]

I made it to the machine room. My friend, who played before me, accidentally put a cog through a wall. I have no idea how it happened. It just went through the wall, and the cogs are needed to make further progress. Does anyone have a save somewhere near this point in the game that I can have? It doesn't have to be in the machine room, just somewhere near that particular point in the game (preferably before). I do not want to start over from the beginning due to a bug.
