Make sure you own the game on steam, or that you are running the game with elevated permissions(running as administrator). ---

Do you have Steam open while you’re trying to launch the game? If you don’t have Steam open, it’ll be unable to verify your ownership of the games. ---

I’m presuming this is a Raw Input Error that is appearing? If so, check that no other instances of hl.exe are running, as that will cause problems with hooking rinput up with the game. ---

Unfortunately, without an error message, there’s not much information to go on. With the previous two steps we could make progress since we found the error, but without any information I’m afraid I can’t help. ---

In the game properties in Steam, go into the launch options and set it to `-w 800 -h 600 -forceres -gl` which will force the game to 800x600, and from there you should be able to get to the settings to change it to what you want. Afterwards remove those options. ---

In Steam again, go to the game properties and force it to revalidate files? It’ll redownload anything broken.
