Anyone with pipex isp know how to recover password?

Quite simply, the peice of paper they sent me with my login details has gone walkies, and I need the info. I have hunted high and low on thier web site for a password recoverery thingy, but no luck. Anyone know if there is one, and if so, where it is? (P.s, there support lines not open till tommorow, so I will call them tommorow if needs be, but I would rather get it sorted tonight)
