My Windows Live Mail 2012 suddenly started opening hanging (Not responding).

But only sometimes.
Have run 'Windows Live Essentials' Repair in vain.
Have done system restores, which sometimes fix it and sometimes don't. 
The problem keeps recurring.
The problem has been almost a week but never had such problems for all the years I have had Windows 7 and Windows Live Mail.

All forum advice seems to straightaway suggest reinstalling if the Repair does not work. I would much rather fix the problem on the basis of the log file than go through all the trouble of reinstalling and recreating the account and all that's in it.

How can I attach log file from C:UsersJanetAppDataLocalMicrosoftWindows Live Mail? I have it in zip form. It is only 3kb zipped. 

I would be grateful for any help in fixing this problem and can send any other logs.
