How do you un lock aq worlds accounts

Depends on what kind of actions you've done, You can't personally unlock it, It goes like this,

If you got hacked and you found out your account has been locked, Contact AE by phone or mail(They usually respond a day later), and they'll have your account unlocked, If you disputed your payment for membership you'll have to add 10+USD to the total price that's been disputed example

$19.95 Dollars = 3 month membership, so 19.95+10.00= 29.00

29.00 Dollars is the ammount that's going to be paid to them in order for you to Re-activate your account
