I downloaded et_beach.pk3, from here,
http://maps.arni.name/etmain/et_beach.pk3 . Put that file in the etmain folder. That didn't fix the problem. Why? Because when I load Beach Invasion, which loaded. After the warmup, before the start of the match. The game would crash, after warmup. But... thanks so much nedd3h! I download the latest 2.60b .exe file for ET. That helped with my problem! Everything seems to be running great!
TomTom, I'm new with ET, not sure where to find the etconsole.log or etserver.log. With not having problems right now, since downloaded 2.60b, it'll come in handy if any other problems occur.
