When I load a video to be edited...  it puts a green film over the video...  the videos are fine no issues with them.. but for some reason, Movie Maker is putting this green film on them... as if I have a green filter on the lens... it don't stay through the whole video when I save it, but can't get rid of it.. WHY   what is happening..  it did not use to do this before...

   I am using Windows Essentials 2012   My windows is  Windows 7 Home Premium 64-bit

  It used to work fine.. now am having issues with it and no idea why or how to fix...  I use windows Movie maker all the time...

   thank you
