Yep, thanksss Buzzz.
Still seems like a bit of a bug though that should be fixable because the final version won't install to:\Terragen 2 Technology Preview (Deep)\
Maybe if I had left my project file directory, hold all files, tgd's, tgo's, bmp's and so forth, outside of Terragen, I wouldn't be having this problem.

If I remember correctly, I think Matt and Jo released the last update on the Friday of a US 3 day holiday weekend. Hmmm
