This problem started about a month ago. When I try to sign into MSN Messenger I get an error message saying," Sorry,We could not sign you in because the sign-in name you entered does not exist or your password is incorrect. If you have forgotten your password, please click help in the main Messenger window, and then click Help Topics for instructions on resetting your password. 0x81000303 " I tryed logging on with other accounts and the same error message appeared. How do I fix this problem??????????
