Kornman V2 guerilla won't start

Okay, hi again some of you may be noticing my constant error posts. This time, however, it is my Kornman V2 that won't run. It ran for a while, but recently it just reaches the Bungie picture that fades in but then flickers and fades out. The Kornman V2 guerilla does not load. Although, I checked the task manager and it says that kornman is still running even tho it is not using any cpu. I have reinstalled halo custom edition as well as the halo editing kit and updated both. Nothing seems to work.
