Source SDK problems

[red_flame586]

First of all, i'm not sure if this is in the right area, if it's not, could an admin please move it to the right place, thanks.

Whenever I try to open hammer, I first of all get a warning saying:

Warning
The configuration information for the game you're trying to edit is invalid or missing

Then when I click run anyway, it says:

Setup file 'gameinfo.txt' doesn't exist in subdirectory 'c:\program files\steam\steamapps\red_flame586\team fortress 2\tf'. Check your -game parameter of VCONFIG setting.

Down the bottom of Source SDK, the engine version is Source Engine 2009, and the current game is Team Fortress 2. I'm running windows 7, don't know if it'll make a difference, but it has never happened to me before and I was successfully was running hammer about 3 or 4 days ago.

I would greatly appreciate it if anyone knew anything about this and how to fix it.

You have to open tf2 at least once first

Also, refresh SDK content.
