I'm trying to post from Windows Live Writer and get the following error:
"Error connecting to blog
An error occurred while attempting to connect to your blog:
Server error - the server reported an error with the following URL:
You must correct this error before proceeding."
I have previously been able to post via WLW without any issues, and did not make any changes to security or settings that I can recall.
