Program freezes after cuda runtime error

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run Exposure Render executable 
2. Select a dataset (any volume out of the 6 in the welcome screen will do)
3. Program freezes. Last message in log widget is "The 'Single Scattering' 
kernel caused the following CUDA runtime error: unknown error."

What is the expected output? What do you see instead?

Expected: 3D Rendering of volume. 
Actual: Software freezes and has to be terminated.

What version of the product are you using? On what operating system?

- Exposure Renderer 1.1 installer package.
- Win 7 (x64), 4 GByte Ram
- NVIDIA Geforce GTX 570 (1.28 Gbyte GPU Mem)
- NVIDIA Driver 285.62

Hi Oliver,

I see that you have the latest drivers from NVIDIA, though, have you tried 
re-installing the display drivers? This may help.

Let me know if it helps, otherwise I will look further.

Cheers,

Thomas
