tu flash.js aun esta mal, aqui te lo dejo de nuevo, solo sustituye el texto de tu flash.js por este y salvalo.
Código:
function RunFlash()
{
document.write('<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#version=7,0,19,0" width="760" height="680">');
document.write('<param name="movie" value="heaven.swf" />');
document.write('<param name="quality" value="high" />');
document.write('<embed src="heaven.swf" quality="high"/pluginspage="http://www.macromedia.com/go/getflashplayer" type="application/x-shockwave-flash" width="760" height="680" />');
document.write('</object>');
}
