When my scenario loaded (with fog), It exceptioned and gave me this error:

Then, I deleted the fog and when typing "radiosity_save" I got this error:

I then ran it in tool:

val\survival survival 0 0.01
i'm going to render debug lightmaps for survival of levels\survival\survival, an
d i'll stop when red+blue+green = 0.010000.
Hit control-c now if this isn't right.

any chance your BSP is curropted? i always get something like

EAX: 0x00000404
EBX: 0xFFFFFF01

when ever i have a curropted tag

I'll try moving/deleting the fog plane. Also, I use 0.01 for most of my lightmaps, so it's not that.
EDIT: Got it to work, thanks! What I did was re-size the fog plane and move it a bit.
