issues with Apple Configurator 1.3 and provisioning (wifi profiles)

I had a configuration profile which worked well using the previous version of apple configurator. Now with the new version something has changed, so it does not work anymore.

The documentation on how to provisioning a profile to the apple TV is still the same, eventhough the GUI and the procedures have changed in "Apple Configurator". Can you please help me, understanding the changes that have been made to v1.3, in order to properly create and provision the wifi profile to the apple tv, as described here: http://support.apple.com/kb/HT5437

thank you
