Until 2 weeks ago I could edit and create movies using .mpg & .mp4 files in Movie Maker. Now I get an error message telling me that the file is corrupt or a format not recognized by Movie Maker. 2 weeks ago it was a recognized format. To be sure the files were not corrupt I tried to edit previously working files with the same result.
I'm using Windows Movie Maker Version 2012 (Build 16.4.3508.0205) on Window 7 Ultimate (SP1).

With the exception of updating my PC's Video Card driver I have done not to my computer.

What could have occurred and how can I fix it?

By the way, the .mpg & .mp4 files play fine in WMM. The problem starts when I try to edit them, (split, start point, etc.).
