Grid For Texture Editor Doesn't Show Up

I was waching a cinema 4d video when he selects the texture editor option on the left and a yellow grid pops up. He can then move, scale, rotate the texture that was applied to a object using the yellow grid. I tried the same thing but all that shows up are axis controllers shown below. I tried to use them but they don't do anything. I tried to do the same thing on a simple solid but that didn't work either. PLEASE HELP.

You need to change the projection to something other than UVW Mapping... That will allow you to see and manipulate the Texture Grid.
