Windows Live Mail recives and sends email. When I am trying to Sign in with my login and password it claims there is no Internet connection. Windows Internet Explorer is working ok. I can access to my Live Mail account at other machine.

When I receive an email with an attachment it comes as a zipped file. If I try to open it a dialogue box pops up that says

View Downloads -  Windows Internet Explorer, then I click on open and the same box keeps flashing. Outlook has gone downhill
