You are in the right place to post; we just need to know what game you are playing.
Here is some helpful advice about the crane puzzle from another GameBoomer:
When extending the crane, I found I had to do this in small stages, eg. click the lever, let go, click again, let go until the crane has extended all the way to the open window. There are at least 4 parts of the crane to extend.
Maybe you could try the above and then see if you still wish to have a saved game.
