Help with Windows Live Mail

I'm having a similar problem to this.

I download and install Windows Live Mail. At the sign in screen, there is an account which I have previously deleted and yet still appears in the list. This is a hotmail account.

I uninstalled the program, deleted relevant registry keys and removed any files I could find left behind.

I also unchecked the "Forget me on this computer box" when signing in.

I then reinstalled Live Mail and the same thing happens again.

Grrrrr.............

Anyone know how to clear the list of sign in IDs or at least clear the ones which aren't in use anymore?
