How to break the password of Word document

I have created one Word Document one year back that was very confidential so I gave password to it. But now I have forgotten and also the manual records are not with me now. Can someone please help me to break the password of MS- WORD document. It's very urgent.

I haven't tried it, but people swear by it. I was going to try the free version for an Access DB, but remembered it.
