I originaly set up Outlook using hotmail.com. I was able to change email accounts but coputer show data account defaulting to hotmail which it says is unavailable. It want let me delete hotmail and it will not let me make gmail the default data base account. How do I correct this?

In addition, Outlook will not open. I get an error message saying "MAPI was unable to load the information service msncon.dll. Be sure service is correctly installed and configured."
