Help me!

I cannot log on.
I logged on 1st time, And I accidentally put a space on my password.
It now says,
"ID has logged in already. Would you like to log in again?"
When I press OK or Cancel, it disconnects me.

I also tried to go on my friends account, It let me log on. Its just something with my account.. :[

Help me pleasee :]

KthxBye
