Problem logging in not sure if its the games fault or if its the doing of a hacker

yesterday i was able to log into my 27 mage acc (tvventyseven) today when i came back to play just like a usually do everyday i get a pop up saying its not the correct password. i am pretty sure i put the right password in but its not working. the email i used to make the acc was a made up email that isnt real. ive tried making the email but it yahoo doesnt give out anymore rocketmail id's. if theres anyway u guys can fix this problem and let me get on my acc i would very much appreciate it :) ty.
