My account does not work in the game, help mee!

My English is not very good, sorry any error

Well, I created my account last week and I went to download the freestyle gunz
all right, but when I access my account IN THE GAME did not work, shows "Incorrect Username or Password, Create a free account at http://fgunz.net//" (Error E10000)
I can not understand What happens, because when I enter the site with my account it works perfectly.
Only when I enter the game does not work !! I'm sure placed correctly the login and password, beacuse I tried several times

Can someone help me?
I think there was some error in the system
