Alright. Let me explain you how to get this addon working by mounting TF2, you little poor guy (lel). First of all, you need to have TF2 installed, otherwise you will see big red ERROR signs. If you haven't already installed TF2, go ahead and install it from steam store. To mount it, you need to click this button in the corner of the main menu of Gmod. Here's a pic: http://prntscr.com/6m34bv Then a menu will popup, which will have full list of games that can be mounted in to gmod: http://prntscr.com/6m34q1 (don't check games that you don't have). Find in there TF2 and check the box http://prntscr.com/6m35q1 (If it's unable to check TF2 in there, it means something is wrong with your TF2 installation). It might cause a minor freezing, but it's okay, because TF2 content is being injected in to gmod, you just need to wait. After that, quit gmod, start it again, start a map (gm_construct is the best for testing this), and have fun. I hope this helped you :)
