I want to thank you for all your help. It seems the source of the issue and how to FIX for anyone who is interested is that you have to have ALL of your VIDEO in one folder and when you SAVE the .vf (while you are working on your project) you have to SAVE to the same FOLDER/LOCATION that your VIDEO is located in on your C drive.
There is also a workaround if you need a quick fix. Open a new project, import your media, edit your media, RENDER your media instead of just saving, close and then open your original project and import the rendered video file. This works too.
THANKS ALL!
