Problem loggin in.

Sometime when I tried loggin, it wont let me. It just stuck there at the loading screen after I press "enter". Usually after I press "enter" it would immediately let me log into the game but sometime it just stuck there at the loading screen. So I tried again and again trying to log in, but it just wont work. Is it just me or did many people have experience the same problem?
