"i downloaded the client FridayMS (a sign of a chicken)"
That's your first problem, there is no client for Friday-MS with a chicken? I believe so... (*Hint Hint, Virus?*)
Also, did you ever think of maybe turning off your Norton Anti-Virus and then trying to run it? Make sure you have the client INSIDE the maple story v83 folder and you are running the Friday-MS Client, Not the maple story client?
-Try completely erasing any previous maple story versions and files and then reinstalling it and ALSO, Make sure your Maple story v.83 is ON the hard drive that you are currently running on, that can be a problem sometimes, what OS are you running and how many bits is your comp?
-Also, may I include, do not demand and threaten for technical assistance on a forum of a private server that we're providing you to play on. Do not threaten to leave and what not because it's not our problem, we can not help you anymore then the information that we know.
GoodLuck.
