Hi there,
I have a very small scene, just an animation of fonts and one other mesh. When I want to render it out as an AVI it crashes. So I figured that the same happens when I hit the play button. The Scene runs with over 80fps so there is absoloutly no high poly mesh in it or any high res texture that might take over my graphic card and force it to crash.
I am getting really devastated here, it´s just an intro for my movie and I am not able to render it out.
I hope I can find some help here 
looking forward to it. Thank you very much in advance.
Cheers
