I spent two weeks completing my video file using movie maker for my husband's birthday surprise, but when I tried to open it last night in window movie maker it gave me the error ""Sorry, Windows Movie Maker can't open this product file. the file might not be compatible with Windows Live Movie Maker or be corrupted. Please select a different project file."


I was saving my work time to time but now I just can't access it at all. I have already reported the problem to Microsoft but no response yet. Please help me retrieving my file as it is very important for me and its for my husband's birthday which is on 10th December 2013. Please let me know what I should do to retrieve it asap.

Thanks,
