Hi,
If you want to see what login data is being stored Protected Storage
PassView
http://www.nirsoft.net/utils/pspv.html will display that data and
allow you to delete individual username/password combos.
I'd try selecting each username from the autocomplete dropdown list (just
put the pointer on it) and hitting the Delete key. That may allow you to get
a fresh start with that site.
Next I'd try clearing all stored passwords from Internet Options> Content>
Autocomplete. See if that resets things for that site.
