hldj.org

HLDJ works well for the rest of my games, but TF2 gets the message "Could not launch game application". I checked that the directory is on tf.
I'm using HLDJ 1.45 since 1.48 is even worse in this matter, since it detects TF2 as a HL game and it uses TF2's cf file as the directory.

Thanks for pointing this out, I can confirm it on my end to. A quick peek on google seems to indicate that Valve's done it again and broke something: tf2's gameinfo.txt has apparently been removed in the newest Steam update (possibly by accident).

I'll look into the issue some more (hopefully they'll fix it soon), but in the meantime please just create a dummy "gameinfo.txt" in your tf directory and start the game manually.

Restart your Steam now, I think they've fixed it.
