(SOLVED) "CD Key authentication invalid for internet servers"

[Buckybomb]

Every time I run a map through hammer, TF2 always gives this error when the game tries to make a custom game.

There's not much I've been able to find to help me with the issue; even following everything in this thread (https://goo.gl/3MDNWf) still gives the issue. If I can't test it like that, is there any other way I can test it?

Thanks.

EDIT: It looks like even when steam is booted, hammer is just by default launching tf2 in an offline mode. I'm fairly sure it's a hammer related issue by this point, not tf2.

Is steam open?

Yes. Steam is currently open.

Try having TF2 open when you start the compile, and in the Additional Game Parameters box type -hijack

This is the closest I've gotten to it working, however another error message appears now:

In that case yo can try one of two things - either verify your game cache or just run your map using the console with the command map [mapname]

Thank you! Running it through the console worked.
