Jeff,
Thanks for using Writer and sorry that you're having problems getting it work with your Typepad blogs.
Which version of Writer are you using (you can find in this in the
Help | About dialog)? If the version number is lower than 14.0.5025.904, try upgrading to the latest version at http://download.live.com/writer.
If you are already using the latest version, try going to
Tools | Accounts, then select the account you're having problems with and click the
Edit... button. A new dialog will come up and there will be a button called
Update Account Configuration...
Try using this button to reconfigure your account and see if it works as before.
If not, please send your log file to
becky.pezely@microsoft.com. You can find your log file by going to the
Help | About dialog and clicking the log file link.
Thanks.
Becky Pezely, Windows Live Writer
