First of all hello all Im newbie in GM mod things I post here to get answers from experts OK..so first I DW GM9 but when I launch it i get typical error I and I read something about changing in shortcut in GM9 icon what should I do there because I don't fully understand that 215 etc :D
C:/Program Files/Steam/Steamapps/Sourcemods/Gmod9/Gameinfo.txt Look for 215 there, changed it to 320. That might fix it.
have you played halflife 2? have you played the games they need you to play you need to play 3 games one time to have access to gmod and get gmod 9.0.4c to play on online servers and make servers and if you dont be happy playing by your self on single player ^_^
