I didn't make it!
Hey ive got this problem that i loaded a couple mods (eclipse - battlegrounds - plan of attack - the hidden source) but everytime i start them the screen goes black and then i suddenly get back to desktop. Wht can i do against it? (i do have hl²)
One problem could be is that the game definition files for hl2 or hl2dm are not up-to-date. If they are, then it is most likely that you have a video card compatiblity issue, I would try updating the drivers and trying again.
