my map wont compile

[becky]

when i try compiling it, TF2 will open, but at the end of the loading screen, it just crashes. i've copy/pasted the map into a new file, putting everything in dev texture, checking the log, and nothing changed. when i tried compiling a different map, everything worked fine. ive grown attached to this map and the last thing I want is to have to start over. any help is appreciated. here are some screenshots

this might be obvious but do you have a skybox?

Paste your compile log into this if you haven't done already and see what it says.

If it doesn't return anything useful, paste it here, preferably in spoiler tags.
