Lots of people have been having problems getting CSverter to work for single blog configurations. With the help of a couple people, I figured out why, and have coded a fix for it. This version also fixes some problems with the web service, and has cleaner logging. The logging and UI status updates are very complex, and are still undergoing refinement.
Please read the wiki page for instructions and assistance. It is highly recommended that anyone using the tool upgrade to this new version.
