adtonomy stopped working

hello,

I am a licensed player & adtonomy customer. A few weeks ago we installed adtonomy which was working great. Ads were pulled out of a database and the adtonomy xml was properly generated.

Today I created a new ad and adtonomy stopped working!? I checkd the XML against the Implemetation Guide but I don't see any error.

I cannot recall any changes made to the site except an upgrade of the main flash player.

Would someone (else) please look what I did wrong? I cannot find any errors. :(

(view source to view the xml)

Thanks in advance!
