i have downloaded a few MP mods for hl2 and everytime i launch a server, it crashes with the error "Unable to load authentication library, Exiting..." i was googleing this error and i got an answer to change the "-applaunch 220" to "-applaunch 215 in the shortcut. now when i open the shortcut it says something like "-gameid 1234567890555" (an examole number). how do you fix this or is there another way to change the applaunch id? I freaking hate steam and it doesn't ever work the way i want it to. i have like 7 different mods that i want to play mp on and none of them work because of this id launch. PLZ HELP!!!!!
