Segmentation fault (SDL Quake)

I got sdl 1.0.1 and sdlquake 1.0.9 and when i run it it initializes a few pak files and the console and then it gives me a “Segmentation fault” error and shuts down, i had it working earlier but when i removed all .c and .h files it still worked but after a reboot it stopped working! I also couldnt when i got it running connect to a lan game or host one, when someone joined it frooze, and when i tryed to join if froozed too. My last question is how to get it to run in fullscreen, i have no idea. THANKS IN ADVANCE!!!
