How to Recover a Word Document

I have fallen victim to a crucial MS Word document that I created becoming corrupted. It looks like the wingdings font when I attempt to open it.

Does anyone know of a good free tool for recovering corrupted documents? Thank you.

Here is a couple of shareware ones that might be able to do it with the trials:
