What errors do you see?

light post, the ground in certain buildings, buildings

Sounds like you're missing content packs. Make sure you got both.

i got both of them but still see errors :/

I also have errors

I need help. I have Half life 1 and 2 and both episodes and Counter Strike Source and I see black and pink missing textures on grass and water. What else am I missing? I have all halflife games and CSS

I also went and got Ev oCities 2 context packs as well

Sounds like a game isnt mounted. Click on the game controller icon in the bottom right corner at the main screen. If EP1, EP2 and CSS are installed, the options to enable them will be available.
Restart the game once theyre mounted

they mounted now. it works
