Hi Maplers,

We are aware that some players may experience the following issues after the v.233 game update maintenance:

• Players receiving errors when attempting to launch/download MapleStory.
• Players receiving errors when entering or making purchases in the in-game Cash Shop.
• Some players are unable to charge NX.

We are currently in the process of investigating these issues and will provide you with an update as soon as we can on this webpost. We apologize for the inconvenience these issues may be causing you. Thank you for your patience during this time.
