Hey everyone. I'm looking for help regarding missing source files in Lightroom 5. Whenever I go to print a photo from Lightroom I can't print. Its like this with ALL of my photos and I just discovered this since I bought a Canon Pixma Pro-100 and just started to (attempt) to print my own photographs. This is the exact message I get: "There is one photo in this print job which is missing its source file. It will not be printed." I have no idea what to even think about this! I get this message with every photo I have imported into Lightroom 5(103 photo's). Am I importing my photos wrong or something? I have no idea... Thanks for the help!
