Well I had the terrain toolkit working for a couple of days, but I must have pressed something I didn't want to as it just shows up as text, ex/ Perlin Blend 1 and it doesn't have the sliders and it is just listed straight down. What is the error? Is there anyway to fix it, or should I just reimport it?
I would say yes, just reimport it (or redownload & reimport if you somehow messed up your original copy locally).
Then come back here and add more detail to your question if that doesn't work.
