Up until three days ago I had Windows Live Mail with both my Comcast.net and Hotmail.com accts. No problems. Then my Hotmail acct quit receiving mail.  The calendar "uploading" message kept flashing down in bottom right. So I uninstalled and reinstalled. Got this " Synchronizing please wait message." For two days. Then I totally uninstalled and reinstalled. All came back the same. Comcast fine. Hotmail "Synchronizing, please wait." Now what?
