This file doesn't exist under PR1.0 that I can see. Out of curiosity, why are you running an older vulnerable version?
because i still need to reinstall my system, and haven't bothered getting an updated version yet (i know, not a good thing, but i'm planning on doing it tomorrow!)

but i will try and figure out where the passwords are stored in the latest version too

[EDIT]well, just installed the latest version, and it appears to be solved here, BUT the passwords are still stored in the same file (signons.txt)![/EDIT]
