Red Crucible Reloaded Missing textures glitch

1. In Red Crucible Reloaded, there's missing textures. I looked up online some solutions, and it said to come here, to Unity website to : "clear cache". 2. I come to the website and try to click delete cache. But when I donwload the Unity Website, on FireFox, it still says: download Unity webplayer. I've downloaded the Unity webplayer 10 times and even restarted my pc. I've looked up tuts online, and all fake. PLEASE HELP ME! 3. So how do I fix the Red Crucible Reloaded's missing textures every where? Even the menu is messed up. Please, help me fix this!
