Macintosh Character Stuck on Character Selection

Yesterday morning, my maple legends was working just perfectly. However, after coming back home from the gym, I decided to maple and my character was stuck on Character Selection. I tried logging into character #2, and he got into the game just fine; it's just character #1 that's not working. Is there a solution to this? I have friends who are having the same problem as me--where they cannot log into specific characters.
