Everything I asked is now working, I don't know why. I changed nothing.
I guess it's magic

My List works ok? That's good, enjoy.

Now I figured out that I still did something to make My List work but I didn't recognize it right away.
At my Netflix account I canceled the so-called Test-Participation and then every list in NetfliXBMC finally worked for me.
Maybe the information helps for future developments.

This fixed my issue also.

Before disabling it would either crash to desktop or just "fail to load" when launched. Switching this off on my netflix account has it working as good as it use to. Nice find.
