This is the path
C:\Program Files\Steam\SteamApps\common\Team Fortress 2\tf\custom

But I know realize that the hitsound does actually but the volume for it is really low. The game won't let me change it above tf_dingalingaling_volume 1.0000

Any way to turn it up?

I have put the hitsound.wav in tf>custom>mycustomfolder>sound>ui but it still doesn't work.
In console I have enabled tf_dingalingaling 1 but it still won't work. I even typed "play hitsound" into console, to that it says hitsound.wav file is missing from directory.

Help please?

Model '(null)' doesn't have attachment 'backblast' to attach particle system 'rocketbackblast' to.

This comes up on my console a lot. What does it mean? And could it be causing frame rate lag?

I get lod of these error messages. Help please. Really appreciate it. :D

How would I turn off the option allowing custom files to be downloaded?
Is it in game or in the steam settings?
