I'm in the same boat. I contacted HappyShops, DHL and Larian. None have responded and the DHL website hasn't updated since the 17th. Of all the CE's I've purchased over the years, this one has been the most frustrating and lacking in communication.
Edit: Just as I posted this, I finally got an update on the DHL website. It still hasn't left Germany...
