Save issues, keeps saying various jpeg files are corrupt …….

Trying to save my movie that I have been working on for two days now. Each time I try and save it as a movie it gets through most of the process and then gives me a message that it can't finish because of corrupt or missing files. When I scroll through and click on the files it says they are corrupt and need to be removed before I can save the movie. I have tried numerous times and every time it names different files as the issue. I have deleted all cookies and tried again, I have made sure that the fix file thing in option is clicked, and I have even removed the files it suggests and then when I go to save again it marks more photos to be removed. I'm at wits end. Please help!
