I cant log into my account >.< I was just hopping world, hit logout instead of lobby and boom cant log in....."incorrect pass/username" They are right.
Try logging into the site. If you can't, it's possible that your account has been comprimised. You may want to use your recovery questions and change your password.
My suggestion: Since you are getting hacked so often reformat your hard drive,get some good a/v and if you're sharing a computer try getting one of your own.
