¡¾Generator begin.¡¿

21:30:07¡¾#3: World kernel thread running.¡¿

21:30:08¡¾Connect to account server again...¡¿
21:30:08¡¾NPC server login OK.¡¿
21:30:09¡¾Account server login OK¡£¡¿
Also make sure that MYSQL is running correctly. This error is mainly from the account server. This is what the errors are and what might be causing them-
Maintenance or congestion error- All the servers are down / oem is not right
Please try later- The account server is up but not he MSG server
Invalid acc or pass- Mysql isent working
