Thanks for both replies guys, now I can delete the installers from my temps. thankfully i hadn't performed the no turning back double click (well I guess there's always system restore, but I hate wasting time, it's the only real thing we have, which is ironic because we can't see it).

Better to get some advice or a tut on Maya terrain construction. I dont know what gnomon is and I am soooo broke you can't believe it (just brouht a you bute laptop) and not much $$$$ is rolling in.
