I Can Not Get Flash to Play On My Site

http://thepoethouse.com/testing/

I’m using the Xtreme Mp3 Player plugin (and have tested several others) but no flash player seems to work. All I get is this white box. The editor is turned off under the user section and I’ve really been wrecking my brain trying to figure this out. I’ve even tried players that I know have worked for me on different WordPress sites in the past and still nothing. HELP!
