Pointsec Problem

Hi, I have a laptop that I inherited from my last company which has Pointsec on, something happened the other day and a message came up saying the password database was corrupt and that I would have to use an old password, when I use the old password I get a message saying “Invalid login, password ok but user locked” What should I do please???? Any help would be greatly appreciated. Windows 2000 is installed on a HP Laptop.
