I used the trial version of Photo mechanic for the first time and now I am having problems with opening my images. (Fortunately I saved them to disc at each stage.) However, my computer says " Jpeg marker segment length is too short, files may be truncated or incomplete." Some of my thumbnails photos changed as I was watching them to generic jpeg icons. I am not sure if it was Photomechanic that caused this or maybe I just have too many images taking up space on the computer. I have never had this problem with any of my other images and it just seemed to happen right after downloading photo mechanic.
