Skyboxes not working?

[rook]

Very new to mapmaking, was following UEAKCrash's tutorials. Got to the skybox part, and it seems to be leaking, even though theres no noticeable cracks. I double checked the numbers I put in for lighting and made sure there were no cracks and yet it still leaks. Anyone have a solution?

load your map point file and follow the red line which should help indicate where there is a leak.
