I am having this same problem. I updated my cloud a few hours ago, but the changes have not gone through to my embedded version. I have used the object tag method of embedding. Here's the code:

<object width="250" height="175" data="http://cdn.tagul.com/cloud.swf" type="application/x-shockwave-flash">
<param name="data" value="http://cdn.tagul.com/cloud.swf" />
<param name="flashvars" value="id=8441@1" />
<param name="allowscriptaccess" value="always" />
<param name="swfversion" value="10" />
<param name="expressinstall" value="http://cdn.tagul.com/expressInstall.swf" />
<param name="src" value="http://cdn.tagul.com/cloud.swf" />
</object>
