I am having the same problem, but I can't even get to the world sever screen.
I go into the document titled "edit_me_before_first_run.bat".
I right click the above file, and choose "edit with Text Editor"
Then, I pasted,
+set wsrv_url
www.coopordie.com/quake2/rpc +set game coopordie +map pregame +bind o wsrv_login (here my name-space-password)
Then I save the TextEditor.
Then, I bout up quake 2 and have no idea what to do. I tried starting a regular campaign game and it was no different. There were no multiplayer servers. I don't know what to do
Anyone ?
