iMessage on Mac OS x won't connect to my Yahoo Messenger account
iMessage worked fine with my Yahoo Messenger account until about a week ago. Since then, iMessage says "Messages can’t log in to xxxxx@yahoo.com because your login ID or password is incorrect. " The ID/PW I enter works fine in the Yahoo Messenger application, so I know the password is fine.
I deleted the Yahoo account in iMessage and re-added it, but no luck.
Any Ideas?
