Yes, you need to download the settings to your PC and insert the sky-de bouquet.
Thereafter, reload the settings back to your STB and don't forget to change attributes to 755.
NB:- Don't forget to add the line
#SERVICE 1:7:1:0:0:0:0:0:0:0:FROM BOUQUET "userbouquet._sky-de.tv” ORDER BY bouquet
Restart your STB and all should be fine
