Neither the installer or manual version works.
When I install it, it has a mix of the default and HUD's look.
When the game first boots up it has the custom background of the sky but when the menus come it has the default TF2 one. I can't even 'Find a Game' because nothing happens when I click it.
Even through the menus which I can go on it has the mix of TF2 and this HUD' setting as said before.

I used to use this HUD but now I can't so the only other option is to use the default but that's terrible and the other HUD's don't seem very good.

I am really stuck, can someone help?
