Gameinfo.txt Error in Hammer

So I've been looking into learning how to map in hammer, and for every single game I have it gives me the "gameinfo.txt file is missing" error, verifying integrity of game cache doesn't get it back and I've reinstalled some of the games, to no avail. Is there any fix for this?

When you run the SDK, click 'Refresh SDK content', and also 'Reset Game Configurations'. I think either of the two should fix it, although it may take only the latter one.

It also couldn't hurt to run each game you are mapping for at least once to generate files needed if the aforementioned method above doesn't work out.

yes the Gameinfo.txt is generated when you run the game for the first time.
