Panic Over folks, I worked it out all by myself. That has to be a "first", lol. For anyone else who encounters the same problem here is my solution. Go to Content Manager. Use the filters on the left to select category, commodity, missing dependancies, true. Ialso tried "faulty" and "faulty dependancies", where I had selected "missing dependencies" prievously. Thinking about it I guess the first two filters could be "location" "local" which would narrow the search to what you have installed. When you find it simply click on it and "delete" it. In my casethe guilty party was Taconite Tailings.
