When i try to get in to maple story after iv downloaded it it just logs me out and says you have been disconnected from the login server why is that

This is a common problem. Check your virus program. If you have Moon secure. delete it and get AVG or norton . these to work with maplestory. If you dont have moon secure and have one of these virus programs i just said . update your drivers. One other way is to delete your virus program even if its not moon secure. and get AVG or norton.
