I'm suddenly getting this error when I try to load up my previous maps to work on. Missing Material 'editor/wireframe'. Go to Tools I Options I Game Configurations and verify that your game directory is correct. Also, whenever I start TF2 regularly, it closes as soon as I open it. I've verified the files of both SDK and TF2, reset my computer, uninstalled ABS' pack, and reset my hammer settings several times, but I can't get it to work. The only notable change that has occurred was a Windows 10 Update last night. I was working on hammer last night around 10 when I decided to shut down and update for windows 10. The next morning, I get this message. Is there a way to fix this?
