Host_init: couldnt load gfx/palette.lmp

anyone know a solution? 8[

you could try uninstalling ESF alpha 2.0 and reinstalling, that way it will replace any curptted files that may of occured during the installation. if you still have any problems, try re-downloading ESF Alpha 2.0 again

Do you know that's an old version of Half-life?
