How to create a map

Hi,
I bought the 1-month subscription to check the available premium features.
I can't open the map creator. If I click on "Create a map" nothing happens, any ideas ?

Html5 editor is not finished, and the Silverlight editor is currently down (can't save maps) but if you want to check it out you need to either install the Silverlight client, or find a browser that still supports silverlight.
