need forum help sign in problems

[A Slayer day]

hey guys i can sign in on this laptop i use for school but i cant sign in on my home computer i click sign in it auto fills it(i've even retyped it) and i get nothing it just says sorry you don't have permission for that as if i was band . well i cant download the bot on this computer because its a chrome book so i can only use this for forums and my home pc for client/botting.
