When I click on Run Map in the File dropdown menu, I get an error message saying:
SteamStartup() failed: SteamStartup(0xf,0x000000000012DD70) failed with error 1: Failed create pipe: 6, Win32 Error 6 “The handle is invalid.”
Even when I try to change the settings, I get the same message. The map seems to compile fine, but I have to manually go into a source game and load the map just to test it. Can someone help me figure out why this is happening?
