I am Multi Lingual and that's why I always try to post updates about stuff we release in different languages than English. I announced in an earlier post that the BITS were available and that it will take a few days/weeks to get other languages. Today we released the German language.
Existing customers can download v4.0 here. If you want to use the 90-day trial in German, you can download that here. You can see the other download locations in the earlier post.
Make sure you change the English language into German before downloading!
