I start a network server the game tried to start an internet connection. The dialog box for username and password appears, but when I try to abort it the game is automaticly closed. Try disabling modem auto-dial in Windows. To use it, open your WIndows start menu, select Kingpin, and then GameSpy Lite. That will load GameSpy Lite, which is a quick way of finding KingPin servers.
Nothing seems to work . . .
This MAY be due the existance of an old glide2x.dll in your system directory, from and old 3Dfx installation. Since the game will first try to initialize the 3Dfx minidriver, this will crash under the above circumstance. The solution is to delete this file, but ONLY if you do not have a 3dfx brand card in your system. The reason we try the minidriver first, is many have installed the Q3 OpenGL ICD for 3dfx cards, which are not compatible with Kingpin. Hearing this I went out and purchased a copy and loaded it on my home computer.
