I haven't used Gmad in a long time. When I open it in my gmod bin folder and press anything it immediately closes. Whats the proper what to use gmad.exe? Edit: Ok I figured out it. You need to shift+right click on the Bin folder and "Open command window here" then type gmad.exe to use it. The only problem is, a Windows 10 update removed that feature so you have to regedit to get it back. I used this tutorial and it worked.
