I install with the (vague) directions given, and I try to open it, but no matter which way I open it, it doesn't work. I tried opening through the N Terraria gamelauncher, but rather than open the game, it just gives me a message to open it through my steam client. I try that, and it just opens regular terraria. I'm using Terraria 1.2.4.1 with the latest version of the mod, which should work. What do I do?
