Lighroom CC 2015 seems to be mixed up, when not allowed pictures to come in to create slideshow. It sees other similar files and is mixing everything up, creating basically a double file. I I have changed the folder position in the computer now when they pictures are imported there all grayed out in lightroom. Can I reset the program? I know by resetting some of the links to already greater projects would probably be lost. Right at this point it's not a concern I just started using the latest version and trying to create a slideshow presentation for wedding anniversary and things aren't working well, help.
