I have made videos using the beta version - they will not play on the current version? What should I do? If I download thecurrent version will I loose the beta version and no longer be able to play the movies i made with it Thanks

I think there should be no problems: the final version is always more stable and reliable than the Beta one. Anyway I also suggest you to post this question in the Movie Maker portal at the following address http://windowslivehelp.com/product.aspx?productid=5 Bye.
