I've managed to get the rage tool kit to install through and building for slowmaps works fine the problem is when I try build a megatexture the builder seems to fall over at the 'processing responses' step.

Sometimes it crashes altogether with a BEX64 error other times it just hangs there. The build logs show:

I've a funny feeling I'm just missing something obvious, it's showing it can't open the .bdm file and the build window has a warning regarding a missing _occlusion.bmodel so I'm guessing I'm missing a step somewhere.

The map is only a couple of rooms, using 4 different textures, 2 ai ghost entities, a weapon entity, a box of ammo entity and a few lights and the slowmap works fine, even loading it as a full map works it just has no textures then so I think I've missed a step in the configuration or the build process somewhere. Does anyone know why it might not be building the MegaTexture ?

Edit: Also when it crashes altogether the bottom of the Map Build Wizard window says "WARNING: No address, error:126" it gives the same error for a preview build as well, though it never shows up in the actual buildwizard .log file and it happens when I try rebuild the tutorial maps too.
