    Whenever I try to run my map in Hammer, CD Key authentication invalid for internet servers pops up. How do I fix this? Thanks.

    I thought the error message only appears in-game. Are you also using the proper Hammer tool? (Steam\steamapps\common\Team Fortress 2\bin\hammer.exe)

    Try restarting the system. That's a rare error message and even weirder on TF2.

    Try launching Steam before launching hammer. I get that error whenever I compile a map and Steam isn't running
