Basically it works. But it depends ... how fast your PC is and of couse how long the password length is - length below 8 chars can be done, equal or above 8 can be done only with Elcomsoft's distributed password cracker.

This program is awful I have been running this trying to get it to recover my password for about 3 months solid and it still hasn't cracked it, it is rubbish. I challenge them to crack this password, it's a shame I can't remember it!
