Unable to play video clips in VideoPad2 correctly

I encountered series of errors and problems with my computer so I decided to do System Restore. When I am done restoring a project file from my backup, the video clips and images are showing with no frame. During the uploading process I got a message stating that some files are missing and the procedure to locate them manually which I followed correctly.
I am able to play them outside VideoPad 2 although some of the files play only the sound part in VideoPad. I am also unable to play the preview of the project. How can I retrieve my project?
Any help will be appreciated.
