Hi, I'm running Windows 10 & haven't encountered this problem before. Every time I try to open any file besides a .wmv I get the message that movie maker has stopped working. I've tried to convert the files to .wmv but it takes a long time since the files are 2+ hours long.

ive tried to uninstall & reinstall with no avail. I really do need this application to upload speedpaints to my YouTube & keep my revenue flow constant.

thank you so much!
