Im completely new to this and havent yet uploaded my site online. Im waiting until its completed to do that.

I want to put this on my site:

although i have no clue where to start. I dont know how to add JW player. I had a rough attempt at this end i got this error message :

Can someone please tell me how i can get JW player on my dreamweaver site with that addon. Im using dreamweaver CS5 on Windows Vista.

Thanks so much
