I think you may have problems here, but let's see what others think.
There's a site recommended by Miles Mendosa (Steve Wright in the afternoon - Radio 2) where you can save all your passwords securely and in one place. Trouble is, I can't remember the name of the site!!
I use a simple Word table to store mine and password protect the file.
Have you tried the obvious passwords to open?? That is the one/s you most use?
