I WAS NEARLY FINISHED EDITING AN 1HR MOVIE & MOVIE MAKER SAID IT HAD AN ERROR & NEEDED TO SHUT DOWN. WHEN I REOPENED MOVIE MAKER & TRIED TO OPEN THE PROJECT, IT NOW SAYS IT CANT FIND THE SPECIFIED FILE & IT MAY HAVE CORRUPTED. WHERE CAN I LOOK TO FIND THIS BLOODY FILE OR EARLIER SAVED VERSION OF THE DAY??????
