Error fetching RSS url

Hi friends

Ive just recently bought your great autoblo script. It works smooth with most of the RSS formats but I dont know why its failing fetching the following:

http://pf.tradedoubler.com/pf/pf?a=1889656&categoryId=14&recurse=true&programs=19008&xslUrl=http://img.tradedoubler.com/images/xsl/rss2.xsl&mimeType=application%2Frss%2Bxml&maxResults=100&firstResult=0

Some ideas? Im a bit desperate searching a solution for this, but no luck yet.

Thanks for your great support!!!
