My iTunes visualizer's(Jelly, lathe, stix) disappeared after installing lion

After installing Lion today, I noticed that these visualizers disappeared in itunes. I went to each individual file in the Library folders and saw that they were not set to be opened by quicktime but another app. Also I noticed that the quart composer visualizer.bundle was not set to open in itunes. I fixed both of these, but itunes still did not recognize them. Not sure what else to do.
