Check the FAQ. Also are you using Steam? And up at the top right below where it says "Welcome,(your name here" it says "Search" click it and search "Server crash" or something similar and see what other pages it finds and check them for an answer. Quoted from the FAQ "My ESF crashes and returns to desktop after a while!
Make sure you have updated graphics card drivers installed on your computer and try switching your in-game Video Mode to OpenGL on a stable resolution." To change to OpenGL go to "options" then "video settings" or something like that and it will probably say "software" mode and switch to OpenGL and if your graphics card doesn't support OpenGL switch it to D3D anything's better than software mode.
