Thank you for your response,
From the research I did online, other users had contacted WII and they gave them the game manufacturers contact info.
I have raised a ticket with WB Games and had an automated response stating average response time of 2 days, so will wait and see & post any response on here for other users.
I have yet to update software as the Wii U is not connected to the internet, will be trying that later this week when I get time.

quick update - ive just updated the software on the wii u & inserted marvel super heroes - still wont load past the marvel shield.
No response from WB - there customer service department leaves a lot to be desired.
Still 2 unhappy boys
