Windows Live Movie Maker - YouTube?

So im just adding a simple first youtube video for my channel which I made on Windows Live Movie Maker (It's a short video 50 sec.) Anyways when I try to upload it on YouTube it uploads just fine, but when it get's to the point of processing it never works. Under the preview (which is just grey squares) it says "processing 100%-processing complete. But the preview hasnt loaded I have been waiting for it to load for about 2 hours. When I click the upload details it stats: "We did not reconize the container format for this file", "We did not reconize the video condec format for this file", and "We did not reconize the audio condec format for this file" I don't know what this means because im not very good with computers but please help and tell me how to upload step by step, or am I doing everything right and YouTube is just this slow?
