Hi! I am new at mapping so this problem may not be problem at all. I mean maybe this is normal. Well my problem is: When i use Source SDK and i try to make a map for TF2 there comes message to me: "The configuration information for the game you're trying to edit is invalid or missing." When i press "Run anyway" button there comes a only a message that tells me something about gameinfo.txt. I also plress the "Help ..." button, and I did everything what relevant quide's said, but nothing helped. Is Steampipe update guilty in some way?
