Need Help seeing the Flash Video on my Website.

None to Novice Flash User and Dreamweaver user.

I have just made a video of about 2 min long and i would like to put it up on the web that im making with a friend, my friend understands about Dreamweaver but he has never used Flash in Dreamweaver all from CS5. So I had done my first video before this 2 min one with I was able to upload, i even found the scripts online so that the video would play, everthing was going well, but when I changed the videos, i changed the path, and everything, It plays find on Dreamweaver and the Live Preview but when i upload it, it does not play at all it just shows the skin of the player but no video. Just a black box with skin.
