I don't have any saves for this game. Best to go back to your last save before touching the windmill, and following these directions from ronrob's walkthrough:
Your task is to turn the windmill so that it is facing into the wind. As you recall the wind sleeve, this means that the windmill should almost be facing you but a little to the left. A big complication is that at certain heights and directions, the levers are blocked and no more adjustments can be made.
My solution, and there are surely many others, is to begin with the windmill facing to the left, due west, and at its lowest position (left lever all the way up). This is fairly easily accomplished. Now do the following:
1. Press the right button twice.
2. Lower the left lever once.
3. Press the right button once.
