I tried to log in to the game this morning, but at first i forgot my password, so i tried alot of different wrong ones, and i read afterwards that it can block your IP for 15min. Now i'm pretty sure i remember what it was, and i've waited a few hours, but i still cant log in. I tried resetting the password from the site, but it says the account has been active recently, so i cant. The weird thing is i haven't played since a few days back.
It really seems like my account has been hacked, but i have no idea how that would have happened as i recently reformatted my computer and cant possibly have any viruses on it. Does accounts here get hacked frequently for some reason? Or is it something else that is wrong with my account?
I'd appreciate any help

Thanks!
