I purchased the \$60 program to earn the Catia Collaborative Mechanical Designer certification, and I am currently working my way through the 3D Innovator course where you have to make the tractor. I am currently making the wheel. The video guide tells me to select the material browser and type in "Rubber" to apply to the wheel. However, nothing comes up when I type that. In fact, it seems I don't have any materials at all in there. I installed whatever the program prompted me to, I am not sure why this is happening and I would greatly appreciate some help. 

I'm rather new to all of this so I'm not sure if this is the right community to post this, if not, if someone could lead me in the right direction I would also greatly appreciate that. Thank you
