try an absolute path for:
The page itself is still loading, its taking minutes. You could have a fat flash file with no preloader which would take ages to show anything and could look like it just wont play.
Still loading... is the page loading completely for anyone?
My vote is the path.
I just tried http://www.cuzc.com/forumbump/index.swf
and nothing happened. So it could be your flash.
I can take a look if you can post the .fla
Could also be your 'script access' fudging with it.
