Cannot get MLX90640 to work with wio

I just got the MLX90641 and the MLX90640 and the wiki program does not work, it stops at failed to load parameters.
Is this a boa or a software or a library error?
Given how expensive this shield is I really would like to get it working!

did you mean this project?
Grove - Thermal Imaging Camera IR Array (MLX90641) -
feel free to tell me more details about your problem or upload your code.

It is ok,. I am recoding the example anyhow and so far it is working almost as it should.
