I just started getting the following message every time I use MS Live Mail:  "To help protect your account information, Please sign in again". 

A box opens with that message inside every time.  If I select the  OK button, it allows me to log in to live mail again.  But if I select the close button it simply starts the live mail software. 

I'm converting from a private email host to windows live mail service utilizing outlook.com and plan to stop using the old service provider at the end of the month.  I've been receiving emails through both accounts for about 30 days.

I've checked both accounts, they've both been normal and both work well.  My virus software has reported no problems during daily scans.

Is this a suspicious box or is something wrong?
