Dreamweaver CS3 has lost all ftp access details from all sites that are defined in the program - nightmare!

Dreamweaver only retains these details now until I quit. This happened after a Dreamweaver crash. Its been around 4weeks and its slowing my work down no-end as I work with many dozens of sites over a week.

Adobe support are worse than useless and as the software is a couple of years old they won't help (due to this I am even more reluctant in considering an upgrade to CS4) - but I think it could be a keychain or operating system issue... if anyone has any tips that would be much appreciated.
