Importing materials, textures and enviroments

Hi, I am new to Flamingo nxt, I have tried to import materials, textures and environments from different sites suggested by the tutorials but it has been a failure. Could someone guide me through how to do it?
Also, Comparing my dialogue boxes from Flamingo with the ones shown in the tutorials, I have notice that mine are missing several tabs and previews of the materials. Is it because is a trial verison?

We are working on tutorials fro Flamingo nXt 5. Go to this tutorial to start:

Does that help?
