Nostalrius Begins - Quality wow vanilla realm (1.12)

Dear nostalrius, i have hard time connecting with my characters Pandore or Kamagi , it can get stuck on "retrieving characters list" or on the end of the game's loading or when i can log in after a long wait, MY CHARACTERS NAMES ARE SWITCHED witch means that when i log on Pandore i get Pandore character with Kamagi's name and vice versa... Maybe u can help?
