Flash won't launch in DW

I have just made a 1mg .swf that looks great in "test movie" in Flash MX 2004
Pro and great in "play" in Dreamweaver MX 2004. However, when I attempt to
preview in browser in DW, I get only a white window. When I published I
generated a .swf and a .html file, which are both in the same folder on my hard
drive. I have not attempted to upload since I can't even see it in DW. In the
past I have made simple animated ads, no problem, but this is the biggest I
have created to date. There is one frame with Actionscript, at the end, to stop
it.

I am on a Mac platform and I have tried both OE and Safari browsers.
