er-installation problem on Kimsufi server

I have one of the new Kimsufi servers with Debian unning on it, and I want to switch to Ubuntu desktop :)

The poblem is, Ubuntu desktop is not in the list where I choose the new Os for the server :S It was when I ordered it, but not anymore. Only Ubuntu server 8.04 LTS..

So how can I change it to Ubuntu Desktop?

Call/mail OVH?

/edit: dunno but I configured a machine 2 seconds ago and Ubuntu Desktop 8.04 LTS 32bit is still on the list for OS (at ovh.fr)
