I have a legal copy of garry’s mod (the latest one), and so does my little bro. we tried to play a LAN multiplayer game (we had no internet whatsoever), and my computer makes the server and everything, but when my little bro joins it, the server shuts down and gives me an error saying “error: no steam ID” or something like that… YES both of our Gmod’s work in offline mode, and YES we have played a LAN game before (with internet).
can anybody help me?
thanks in advance!
PS: me and my bro have seperate accounts.
