The download here http://wordpress.org/extend/plugins/wordpress-thread-comment/ still works for me. This might sound funny, but have you checked where the browser downloads to? I sometimes click download and thought nothing happened, when in fact the download was so quick that I didn’t see the download popup and then later find that there are several copies of the file in my download folder.
Or maybe you can try a previous version at http://wordpress.org/extend/plugins/wordpress-thread-comment/download/
If one of the download works, then you can update it via the WordPress Plugin menu of your blog.
PS. This code didn’t display right because of the forum formattin
blogname Reply to ‘[postname]’
but I think you can work it out at the options page.
I’m not sure if it’s a typo that’s why it couldn’t find it. My Settings > WP Thread Comment > Edit Comment Form ID says ‘commentform’.
