new to game, game wont open

Okay guys, i want to start on this server. i just recently left Sydney MS, because i'm fed up with them, So i've decided to join this server. i would appreciate a walk through of how to install this server though. i downloaded the "client" and put those 3 files into my Nexon folder, however it pops up, and says i'm missing WzMss.dll...i've tried it many times and it continues saying this. what am i doing wrong? can anyone help me?

Did you go to the link in the readme? It puts Visual C++ onto your computer, and usually fixes that "missing WsMss.dll" problem.
Did you put in the file called WsMss.dll in the first place? There should be 3 files not including a notepad file that ALL go into the Maplestory folder. You need to say yes to replacing WsMss.dll, because that's something used to bypass gameguard.
Just noting, the server's kinda down atm so don't expect to be able to go INTO the game for a while (but once you're inside, you'll find that we're MUCH better than SydMS)
