Hi there Chris,
I’m having the same problem as you had, and i tried deleting those cache folders from WLM, but that method did not work for me…
I just tried to delete the registry key, but i still don’t know either if it worked or not..
Do you have any idea why deleting the folders didn’t work?
When i delete ’em and try to login into MSN, it just do not login.
I can only login again using webmessenger or other programas.
