I have Lightroom 5 and it was working fine on Friday and then on Saturday I went to use it and the live preview isn't working.  I move the sliders and it changes nothing in the preview, although I can see it changing things down in the film strip.  I uninstalled and reinstalled it and reset the preferences and it is still frozen and eventually goes gray after I try to do too much.  What would cause this?
