I softmod my wii 2 years ago and it was working with all just dance cds I get but noe it has problem with just dance 2014 and gives me error 002
is there any solution for it.
You probably have to remod your system. If you have a mod from 2 years ago, you are likely out of date.
If you want validation, post a syshceck. If you just want to trust my gut and go with the update, then see the Softmod Any Wii Guide for directions on how to remod your system to get it current.
