UniWii dll building executable error!!

ANYONE!!! This is very important as it's for our final project due tomorrow! We made a game in unity using the Wii plugin. When we try to create an executable of our game we get an unusual error.

The error is: dll is not allowed to be included or could not be found.

We think this is because you can't create an executable using the wii plugin without purchasing the license for publishing it, but this is just a theory.

If anybody has any answers for us on how to fix this problem, or if you know that or theory is correct than can you please help us? We appreciate it guys! thanks.
