L4D Sdk Problems

[Full Life 1?]

I'm having some problems with the left 4 dead sdk. Every now and again, when i load up my map, decals are turned random colors, police barricade models have black where there should be holes, and every time I select something, it turns black. It really annoys me, and I need a way to fix it so I can map properly again. Screens included.

Thanks for any help!

Is "every now and again" equivalent to "immediately after a L4D update"?

It's been a while since I mapped, but if I remember correctly after every game/SDK update you're supposed to launch the game once to more or less re-calibrate the content.

No, it happens all the time, and I have started the game a lot of times since the last update.

This is because the SDK has already been released. Valve has stated a number of times that the current authoring tools will get an update that will allow map makers to update their map, with little work, to the new game.
