What do you mean they won't open? Please be more specific so someone can try to help you.
Are you getting an error message?
Is it happening when you are trying to log into the email (and you can't)?
Is it just that the emails themselves won't open?
Does the gmail.com page even load?
my email address wont open. only the yahoo is opening but my hotmail when i try to log in it suddenly not connecting to internet.is there any problem in my setting? thnx
