Do you close the calibration file, in the task manager, before trying to run it again?

Have you tried also disabling the firewall, and google softqware running in the background?

>>Do you close the calibration file, in the task manager, before trying to run it again?

I tried both. If i close calibration process in task manager, the second time i run won't show anything. If i do not close, the second time i run will show the freezing screen.

I already tried but the problem still persists.

One more thing: The first time i run, there will be a brief spins on cameras' LEDs and stops with numbers displayed. (1-3) I am not sure if these helps.

Do you currently have the hardware plugged in?

Yes, I have.

Try unplugging the devices, restarting the system, then try starting the software, from a fresh boot, without the hardware plugged in.

Another thing:

The OptiTrack SDK sample crashed when i selected "Multi" in "IDD_CAMERA_LIST" dialog box. It doesn't have the same problem when i opened each camera individually using "Open" in the same dialog box.

The "Multi" button may be using a feature which is no longer supported, and should not be pressed. We will get that removed from the sample.

Nothing happened (no window) after i started the program.
