Problem Screen :
Recently google changed thier security policy and it blocks access to the blogger from all external tool like live writer or any other tool which can be used to write blog posts.
What you can do to over come from this issues is,
go to https://www.google.com/settings/security
and then go to the section Account permissions and click on Settings against “Access for less secure apps”
Here you have to enable the “Access for less secure apps” and click on Done.
Now you try to access the same.
Let me know if anybody is still facing this issue.
