i downloaded windows movie maker yesterday and here's the issue: i can import wmv files (i converted all my video files to wmv via freemake which i thought would be fairly reliable; i even converted all the ones that are already wmv into new wmv files via freemake, which is very telling of my level of desperation) into the movie maker, i can play them (there's audio AND video) in the 'collection' box directly, but once i drag it into the timeline to be edited and i play the video in the timeline, there is NO video. i can still hear the audio part but the video itself blacks out, which is very puzzling because it plays just fine when i'm not trying to edit it. i hope i make sense...

my laptop is barely two months old and i use windows 8.1. i downloaded the maker from http://windows.microsoft.com/en-au/windows7/products/features/movie-maker yesterday. 

would really, REALLY appreciate help; many thanks in advance!
