Unreal tournament editor crashes when clicking play

Just installed editor and it crashes when clicking play. Running example level. Gives this error code:

MachineId:F2EE3B244E43BE598F7BEAAC45245CCB

any ideas?

I have same thing on my desktop machine at home. workstation at USC it runs fine though. still trying to figure it out.

Is that only error text you get? Does it provide you with more text? Could you post additional text please?

I have exactly same problem, but this mornig was working great, now again it doesn’t. Is there any solution??
