The one good file that I did manage to load now works. I have to run the uninstall twice with a reboot in between. I think the uninstall also leaves files behind that don't work with 3.0 as well. As well, it does not install well upgrading 2.2.4. Since the dev does not use standard file locations and 'fixes' some file locations it is probably good to run the uninstall twice with a reboot.

This however does not explain the 400 bad request at 98.53% when attempting to download from their site. Don't think it is an overload situation but a server reboot might clear the issue.
