I'm getting a "wrong user name or password" error.

I've installed subsonic on windows xp, unfortunately i don't manage to log in.
I've logged in as admin after installation and entered a new user name & password, now when i try to log in again, i get a "wrong user name or password" error! i uninstalled, cleaned all registry entries, then reinstalled subsonic but the problem remains.
how can i change or recover my user name & password?
