I was having a problem with all the content I had installed and decided to completely delete DS4Pro and all content to simplify my content management for a major project. Everything went fine, I uninstalled DS4 and My Library. I reinstalled DS4 and everything looked good, but in the Content Library, I am still seeing the name and category file names for content that is no longer there. The content windows are blank except for the name of the file that is supposed to be there. How do I get rid of these empty catagories?
