ERROR 2003 (HY000): Can't connect to MySQL server on 'localhost' (10061)

to start with i was letting CMD load the "source load_system.sql" then after awhile it says that couldnt connect to mysql server so i retry and when i try to get back in to MYSQL with cmd . the error shows up not sure if it the connection or mysql...

any ideas?
