Please help! LR develop module not loading...non technical person here! Since I last imported pictures with no problem a few days ago and now come back to edit, the develop module is completely unresponsive. I can see all my presets and sliders but at the top of the picture I get the message "the file could not be found" even though my library is in tact. This is completely frustrating to me and I am not very technical so any layman terms to help fix would be most appreciated!!!!
