I put in "The Pika" and the my password and pressed enter and it said user not found then i tried again and it worked...
OK, I 'm pretty sure I know what the problem is. I tested something.
When you put the wrong password, it says Pass not Correct. When you put the wrong username, it says User not Found. You probably put ThePika or forgot a letter or added an extra letter.
The problem could be that your account name was switched like now your name is Gligurr . It happened to me when I put Keldeo Infusion in and I had it changed to UltimateFusion8
