catmull rom cameras HELP!

I downloaded this tool but I cant get i work! I have put in everything in my garrysmod map but it dosent work.

Help!

I put it in both steam\steamapps\user\garrysmod and steam\steamapps\user\garrysmod\garrysmod\addons. It didn’t work for me at first but I started putting it in random places and then it suddenly started working. Hope this helps. I think it mainly goes in steam\steamapps\user\garrysmod though.

Hmm… I have put all the maps in addons, materials, lua, vgui but it still dont work. I have in the game (in my tool column) all the tools to make a moving camera but I just cant use them.

Pleas help!
