How exactly? The readme didn't really say how to use it, so I simply installed it to my addons folder and then attempted to paste it into my lua autorun after that didn't work. I've installed it on both computers and neither can host without the other one connecting and crashing it. The torrent also came with a "garrys mod ipt translator" or something, that also doesn't seem to work correctly. I could upload both of the addons if want to take a look at them.
Also, like I said, we connect to other cracked servers, so I don't think it's clientside. Its the server control stuff, (which I know extremely little about). We just want to play lan so we can set the rules and just be with each other, without and lag.
