Flash 9 Security update & Crossdomain.xml

HI,

We are struggling with a small problem since the Flash 9 plugin has become available. The website: http://www.impartproductions.com/Jump/ is using a webservice to import data into a flash site.
For some reason the data doesn’t load, due to the crossdomain.xml file security changes flash 9 has made.

Is there anyone who could fix the crossdomain.xml file with the right settings? http://www.importpartners.com/crossdomain.xml

I have tried some things described in this article, but can’t figure it out right…
