I'm having issues is retrieving the older posts. In WLR, I click on Open, then select a wordpress blog and try to open the last 500 posts. It fails with the following error. I can retrieve up to 100 posts. Not more than that. What shall I do to go back to say 403th post?
"The response to the metaWeblog.getRecentPosts method received from the blog server was invalid:
Invalid response document returned from XmlRpc server"
I'm running the latest version of Windows Live Writer and I'm not having this issue. Perhaps there's a DB problem with your site around that time frame - have you tried DB maintenance on the DB for your Wordpress site?
