Can't view wmv file to resize it when inserting file to our web page, but shows in IE 9; any suggestions?

We use WebsThatWork software for our web page. I upload wmv files to a page so when it's viewed, a person can play the video. When I follow the steps to upload it, the wmv file "box" doesn't appear so I can resize it or even see if it's there or not.
