We might be getting to something here. With those version numbers you've listed, are those all from the 1.6.0004 installer? The way we do our versioning is that the 1.6 is the main product version and the .0004 is the installer build. The installer build will contain the EXE files that have auto-incremented versions like 1.6.3047.37036. However, if everything you installed was from the 1.6.0004 installer we must have some incorrect download link on the site somewhere.
