Webplayer not working for Unity 3 (but did for 2)

Hello,

I just got my website set up, so I uploaded a game (.unity and .html) I made from Unity 2.6 to a hidden page on my website, then copied the .html link location, and posted that on my real page and it worked perfectly. Then I did the same thing with a Unity 3.1 and 3.3 project and it said that it failed to download data file! When I clicked the error details it said that download failed, try again, and when I do it says the same thing! Any ideas?

Thanks in advance!

BUMP, please help :o

Here’s a picture of my error.
