This is a Terragen "Classic" issue...no nodes in classic !! tsk tsk !!
And... there was a discount for registered users of Terragen classic, not sure if it still applies...haven't been to the Planetside website for a while..
hang on...
click... type... click....scroll... read...hmmm.. looks like it no longer applies..but you could always get in touch with Planetside..
