Hi don't worry mate its always a hassle getting a new box and not knowing stuff but basically everything is the same with both boxes.
my advice to you now is to do a factory reset and start over again as you may have altered and adjusted stuff not for the good.
start with a clean box and enjoy the challenge don't let it beat you..guys on here will go out of their way to help you mate so you will without doubt get there in the end.
please tell us what image you have installed and will guild you through it once you reset box.
you will need to download to computer dreambox edit and dreambox control center.and then we go from there.
p.s I just had a thought if you flash this image everything is totally all set up for you..its already pre configured will save you a load of hassle.
