When I configured my blogengine blog to windows live writer, one site (http://download-songs.in) it worked without giving the meta weblog link, just the URL, username and password only.

But when I tried to configure the http://krishnan.co.in/blog it asked for the type. So first I gave the Metaweblog API type and what happened finally was the Windows live writer failed to delete the temporary post it created. Then I tried to configure the same blog with the same configuration with just one difference, that was the type I choose was Movable Type API, it worked fine.

the API link will be the Meta web log for me it is http://geekiest.net/metaweblog.axd
