Why and How

Windows XP - Newest version I-Vault (:SAD)

I was logged into my I-Vault and had to shut it down to re-boot my comp. I re-opened I-vault and tryed to login using my master password and it says I’m typing the wrong password. It is not wrong, its the same password I used to logon 30 minutes before re-booting.

Can someone explain why and what to do to get back in? (:AGY)
