I'm getting the same error on this.
The WiiU has been playing fine up until Sunday.
I was playing in online multiplayer and it gave the 150-1031 error.
The disc has no scratches, no nicks, nothing. It's immaculate.
Pull the disc out - play a level, and at the transition screen between races is where the error pops up.
Repeat - same thing.
No other games seem to be giving this error.
Will Nintendo let me download the digital version of the game until a good fix for the issue comes out?
Game is not even a month old.
Please let me know how to proceed.
Thanks.
