Banned?

Hey!
I was just wondering why i get that i'm banned when i'm trying to log in? I've never used any 3rd party program, nor on private servers or or retail. It's been be and my lil' brother playing since Thursday last week, and i'd hope you admins could help out, don't want everything to get to waste! Let me know if it's anything i could do for you.

Kind regards, ex3emealle.
