Failed to Update Protection Modules Error! - Code [0x30000090]

Okay, so i have been looking at all the threads about error codes with ca but no one posted anything about the error code [0x30000090].I have tried uninstalling and reinstalling the game but it still doesn't work. I'm posting a thread asking people who know how to fix this error to tell me and other people who have this problem a step by step instruction to fix it. Thank You!

I think that code means your ip has been banned. atleast thats the one my little brother got and nexon told him he was ip banned for opk.
