Spout receiver crashes immediately

[Cholerajim]

Hello
I'm a complete novice, but whenever I play the demo sender setup in Unity the Spout receiver crashes immediately. Both the Spout demo and Spout inside Resolume crash. It happens no matter what kind of texture format I use.
I use Spout2 v004 and have tried it with Unity 5.3.3f1 and 5.0 version.
Again: I'm a complete beginner so I hope it's not to stupid of an issue

Figured it out. It has to do with spout not being able to work between multiple graphic cards.
