TF2 Content not mounting

I’m not sure if this is because of the 157 update so I’m putting this here. I have the little box thing checked on the main menu, but no content shows up ingame. I’m unable to spawn any TF2 models, or see any TF2 textures.

I have the same problem. The problem is this:

If you try to launch TF2 and It says “validating files” then Thats the problem you need TF2 to validate files for some reason. This is the only way to get TF2 content working.

Avoiding validating files is when you are about to turn off your pc/laptop Make sure you exit steam. And you can also de frag TF2’s files
