Problem with the demo.

First, forgive my English of Google translator XD
I have a problem with the demo, particularly when selecting the type of engine cylinder head and valves (depending on which one you select, fails or not), a message giving error and closing the demo.
The demo is downloaded directly from the website. I have Windows 7 pro 64-bit hardware quite powerful.
Attached pictures now, I hope you can help me. Thank you.
