I placed the files that I downloaded from Megaupload and then placed it in my garrysmod/garrysmod folder, but then I tried to play multiplayer to see if it worked, and its not working at all now :|
EDIT: I got the Multiplayer working, but I'm guessing it didn't work, because I went into a Dark RP place, and I saw errors where trees were, and purple and black dots where some of the walls and sidewalks are. And there is no road. Just sky :|.
What does not work?
I'm pretty sure Gmod/Stalker RP and the thread exactly above this thread in The Cordon...
You must put the folders with info.txt into the addons directory.
I don't really know what you mean by putting it with info.txt... but I can find the addon folder.
I'm guessing its pretty important, since I put it in the addons folder in garrysmod/garrysmod, and I still get those purple and black squares and errors.
