Ok, wow... I put that in, and I successfully connected to it. No other players were on at the moment though. I tried goin to Internet under find servers again, but still, "There are no internet games that pass your curent filter settings". However, under history, this server that I connected to was listed. Does this solve any mysteries? Anyone have a deffinate answer now? Maybe someone can try playing on that same server with me, to see if I really connected properly.
Update: A friend told me that I might not have the serverbrowser file, located in the platform folder. Lo and behold, I don't even have a platform folder. So, just on a hopfull whim, I copied the platform folder with the serverbrowser from Half-life 2 deathmatch, and put it into GEsource folder. Unfortunatly, that didn't work either.
