How to put a demo online?

Okay so I made a game (not close to being done, but playable) and I have it built and everything into a web format. I saved it on my desktop and have one folder with two files:
Webplayer
Webplayer.unity3d

I uploaded the Webplayer (only) to dropbox then clicked on it but game wont load, even after 5 minutes. Am I doing something wrong?

If so can you please tell me whats going on and how to fix it. It will be greatly appreciated!

Thank you,
Wade

As far as I know you have to upload both files on the net

what i had to do to play it on my site was upload the html file with the webplayer file and open the html file and it should load the webplayer file
