Let's start with making sure you do not have caps lock on when you type your password. We have verified that there are no sanctions against your account at this time and nothing is preventing you from logging in.

There are no current sanctions against your account either megzyt10.
If this problem persists, and you've made sure that your capslock is not ON and that you're carefully typing in your information but it is still telling you that it's incorrect on the game launcher - send an email to support at the address support@wizard101.com and let them know that you can log into the website, but not the game.
