Idk why it does that.

Please help! ;/

Do you have Counter-Strike: Source?

Probably a case of the bad drivers and a missing of certain games.

Reinstall Steam and all the sourse games you use for Gmod, turn steam cloud off, and then try it. Make sure you have the right games for the map.

I got the day of defeat source for the gmod. ;/ and ima try 2 reinstall all games

You need css.

Wow, waste of my 10 dollars.

No, you need CSS to play that map properly. Just play a different one.

his game requires that you own a Source engine game such as Counter-Strike: Source, Half-Life 2, or Day of Defeat: Source.

Thats what it says, So Day of defeat source, nd I bought it and it still does it?

We’re not say to get the game because it needs it, it requires css to play that map, just play a different map that doesn’t require any game that you don’t have.
