Movie Maker, Trouble with Video clips, Rotating when saved

Every time I save my project (which consists of about 5 video clips) my videos become rotated sideways. I can't figure out what the problem is. The clips themselves are saved on the computer in the correct orientation, they are edited in Movie Maker in the correct orientation but when I click save project, they get turned sideways. I have tried saving the project under many different settings. I have tried to convert the original files (.mov) to .wmv files and then reuploading them in the project but then they do not play at all. I'm lost as what I can do.... please help!!
