I edited a video in windows movie editor, but now it won't play on anything else and I can't upload it to anything [like vimeo], despite the fact that vimeo recommended it to me to use (and it's all I have access to)
Make sure you've followed the link 'save to my computer' under the heading finish my movie. Sounds like your trying to open the project file. But if your opening a wmv, then you've stumped me. Hope i helped.
