I have tested in few computer from different location and it is working fine.
Can you click this link and see what happens? If asked to chose player, chose Real Player
My computer doesn't open that link either. I'll try another computer tomorrow and let you know.
Right click into that link, save that link to your hard drive, open Real Player, go to File Menu, Open Menu and point to that file and try to play that file. I think you can force it to play by this way.
