Hey Ray, I have always been having trouble with downloading custom content and I was wondering if you could help me. I can't take a screen shot of my monitor and all attempts of pasting a photo from my phone to this comment isn't working, so I'll just tell you what folders I have open.

Windows (C:)
Program files (x86)
Steam
Steamapps
Common
Team Fortress 2
tf
custom
I've named my hud folder HUD
and then the hud archive.

I have followed all the steps and the hud still isn't working. Any tips?
