Green preview of death and sorrow in movie maker

So heres the issue, recently while editing some clips in windows movie maker I attempted to upload some more footage to my current project. When I did this all I got was a green screen with the audio. Things I've tried to fix it with, uninstalling and reinstalling graphics drivers, make sure my version is the newest movie maker, run the microsoft fixit codec pack for the issue, uninstall and reinstall movie maker, simply restart my pc, converting the footage to different formats (WMV included), and then as a last ditch effort, ask movie maker to work properly (Yes I said please). So, anyone have any idea on how I can fix this? I'm about ready to smash my computer.
