When the CK first came out I did not have too many problems with stability. Due to circumstances, I had put modding aside for time, but now I'm back at it. It takes around 30 attempts to get the CK to start and not crash. Basically, the CK starts up the main window and the rendering window appears, but nothing else and then crashes. I've tried uninstalling and re-downloading the CK.

Apparently, the CK is very sensitive to graphics card drivers. I updated them on a whim and it works.
