Gaming Lego update for Knight rider, Titans etc

[tkdkat]

Hello, I've been googling for days for an answer but cannot find one, I recently updated my Wii U to Haxchi and CBHC and installed the Lego dimensions game I have run the DLC and updates from USB helper but when playing the game it is not accepting knight rider etc. When I look at updates on main screen it says coming soon next to it (Batman story pack also). I'm on Lego 2.41, I have tried running NNUpatcher then playing the game but still get a network error cant connect. Does anyone have any ideas on how to get it to update I didn't want to unblock the DNS as I don't want to update to 5.5.2. Really need it working by Christmas for my nephew..
Thanks in advance for any help offered.

Have you tried download the dlc through newnusgrabber or jnus downloader?

..sometimes one tool is not enough.

Thanks Ive tried NUSGrabber and the latest update is v336 which is what I have. Is it the updated DLC I need for the new packs to work..Can I get DLC through NUSGrabber?
I kept getting an error when trying NUS Downloader
