Here's the problem. I've made a video of things I've did this weekend. After publishing it, I uploaded it to youtube. The problem is that it didn't turn out the way I liked, so I deleted it from youtube and made some changes to the file, then published it again under a different name. However, there was an error when trying to play it in wmp (my first video worked). Windows Media Player could not open the file. So I decided to call it a night because it was getting late. The next day whenever I tried to publish another file, it would crash, leaving me a message reading "windows movie maker has stopped working". After that the program closes. What I want to know is how to resolve this problem, and be able to play my wmv files on wmp. That way I can know if they'll be able to work on youtube.
Sorry, noob at movie maker here.
