Simple Question - Unable to view SWF's created in MX2004

Hi, this is a dumb question, but I’m stumped. I’ve used regular MX for a long time. I have now started using MX 2004 on my laptop for work and for some weird reason I am unable to see any work I post online with this comp. I have to check all my work from other computers (From which I see everything just fine). I’ve tried all browsers, (Firefox, Netscape, and even IE) and nothing. Any ideas what could be causing this? I just get an emtpy space wherever the swf should be displayed in the HTML file.:h:
