your account http://www.aeriagames.com/user/babyboy1992
is not banned so you should be able to login and play.
did you try to do what I wrote earlier? log out from Steam and close Steam. then start the game with NWZLauncher, located in C:\AeriaGames\AVA ?
or did you have more aeria games accounts and some of them were banned? maybe your IP is blocked because of that.
edit: if you cannot login to babyboy1992 here at this forum then you most likely won't be able to do so in A.V.A .. write another ticket that you can't login to babyboy1992 from the website. I guess this might be problem with your aeria games account and not a.v.a
