WiiU error 160-1400: Please help!

It has been working fine, I never get any errors. Suddenly, when I tried to play Smash today, this message appeared:

An error occurred while reading the disc.
For help, make a note of the error code and visit support.nintendo.com.
Error Code: 160-1400

​

Someone know how to fix it? I don't live in the US, so I can't just send it to Nintendo for repairs.
