constant "could not log in" messages


New Email
I recently had to change my hotmail password as someone hacked my son's PS3 account and it was my email address my son used as he doesn't have his own email address.. Now I am constantly receiving the following message to my android phone "the username or password for **** (my email address) is incorrect. Update them now?" I'm given an option to cancel or proceed and so far this morning I've cancelled this message 14 times! Any ideas how I stop this annoying message from coming through or why im receiving it constantly? Thank you in anticipation:(
