rgbd slam crashes and weird behavior [closed]

edit

Hi, I have been trying rgbdslam and got the GUI to run but I dont think im getting the normal behavior. For example, The GUI keeps saying

waiting for monochrome image...

waiting for depth image..

This only changes if I put my hand in front of the kinect and it starts mapping what it sees through the gap between my fingers. If I take my hand farther away, like 30 cm, the camera viewers stop like the image is frozen. But it starts moving again if I put my hand closer again.

After moving my hand around, close to the kinect, for some time, it crashes and its last words are:
