I have used Windows Live Mail for a long time, logged off yesterday and tried to click on today, nothing happens.

I have logged into my Microsoft Outlook account and can see the mails still in there from yesterday and earlier, and several new ones for today, these are usually configured through to Live Mail with my other email accounts,  ( I have email addresses with BT and they all usually open together in my Windows Live Mail each day)  but today I  cannot open Windows Live Mail at all. 

Usually opens within a few seconds, but today, nothing happens when I click on Windows Live Mail.  Any suggestions please?

Moved from Windows XP
