Thanks to both of you. I've used the windows command prompt at work so I know how to get there. I just wasn't sure that's what was being discussed.
I have removed all the plugins as directed above and reimported all the new ones again. It did save my customizations though so I'm not sure they were removed completely.
Do I need to be in the Calibre directory or can I run directly from C:\ ?
