Your computer saved the file with the wrong file extention. You need to change the file to .wmv. If your computer will still not play the video, then you need to either download and install Windows Media Player, or open any folder, click on View and then Folder Options. Select the File Type and click on New Type. Specify the .wmv extention and open with the Windows Media Player program. If you can't figure this out, go to Windows help and study up on file extentions. If you know how to do it, this whole process takes a minute or two.
