Unable to edit / duplicate default materials

[numb3r]

I'm running LH3D 3.3.1 on mac and I'm unable to edit any materials. I'm also unable to duplicate exisiting materials to create new ones.

Neither of these options are showing up when I right click. I am not having this problem in my older version of Live Interior..

Here are the only options (attached) I'm presented with when I right click (this is true for ALL materials, default or new)

Hello!

It seems like you have Std Features only.
All supplied materials are read-only. You may create your own materials.
To be able clone and edit supplied materials you have to upgrade to Pro Features (you may do this via in-app).

OK, thank you.
