Problem getting inmoov or tracking script in myrobotlab to recognise camera.

Finished printing my right arm up to elbow for my inmoov robot and have an arduino clone ( freetronics) board and 12 servos and can get reaction in myrobotlab from servos connected to thumb and fingers.

Trying to get the program to recognise my webcam for tracking and servos respond but camera does not show up in opencv window.

I have tried 2 webcams that I know work in other web cam programs.

Do I need to initialize the camera to work under myrobotlab and if so how do I do this.

I have my webcam connected in a usb port and the lights are on around the camera so it is getting power.

I have tried just the tracking script in myrobotlab and servos respond but no camera.
