Try:
<object width="540" height="30" data="http://uendi.com/wp-content/uploads/2013/12/Text.swf"><param name="wmode" value="transparent" bgcolor="#ffffff" /><embed width="540" height="30" type="application/x-shockwave-flash" src="http://uendi.com/wp-content/uploads/2013/12/Text.swf" wmode="transparent" bgcolor="#ffffff" /></object>
Update both #ffffff spots if your background is a different color.
