feed format sigpro is not working

[Feedburner format]

I want to include the JS version of this feed in my website, but the format=sigpro is not returning in JS format.

This is the url I am trying to include:

http://feeds.feedburner.com/greedyAssociates?format=sigpro

This is js code I have to call the RSS feed.

<script src="http://feeds.feedburner.com/GreedyAssociates?format=sigpro" type="text/javascript"></script><noscript><p>Subscribe to RSS headline updates from: <a href="http://feeds.feedburner.com/GreedyAssociates"></a><br/>Powered by FeedBurner</p></noscript>

All other feeds covert the feed into JS , while giving format=sigpro : eg: http://feeds.feedburner.com/blogspot/bVDtI?format=sigpro.

Please help me understand why this url 'http://feeds.feedburner.com/greedyAssociates?format=sigpro' alone  is not working .

Thanks

I had similar issue. I figured out that you have to set up the feed by "Publicize" tab. After saving changes it's started to work.
