Hi Natalia,
Thanks for following this up. This happens for me when I try to upload certain models, especially VRML files with colour values assigned to nodes.
Although I believe the model is okay, after some time I receive an error message by email like the one attached.
The problem appears to be a combination of model complexity and colour/VRML, since the model uploads fine without colour as an STL file, or if I lower the polygon count.
It's notable that previously the Shapeways software has managed to calculate the cost correctly, but the image didn't get rendered, making it seem like the problem occurred during the render stage (which tallies with what Paul suggests in his email).
Thanks again for looking into this. It would be great if there's a fix, since I guess it would allow for better quality prints to be created.
