I'm able to use MS for 2 - 4 days, then it will not open. After several attempts to open program, I can't open it. So, I uninstall and then reinstall. In a few days I get a note that I need to update. I follow link and install the app. Everything seems ok and I can open the app and read mail. After 2 to 4 days, the cycle begins again. How can I get the update to work? I'm running Windows 7 home And gave used MS for several years and really like it. Any ideas????
