Well i was finally able to update the firmware, but i discovered a problem between the Codemeter-Updater and the firewall Netlimiter 2 Pro. Netlimiter seems to block any connection attempts between the stick and the TCP/IP connection to the internet - Even if u deactivate the fw !! Only an uninstall has helped me - So if u use Netlimiter and also have problems - Uninstall is the best option
