Doesnt work

I used what I thought was the correct word, and it didnt work. I was confused so I used the hints, turns out it was the exact word that I entered in the hint box. I tried to re-enter the correct word, and still was not able to enter the correct answer even though I knew it was without a doubt the correct answer. Good idea, it just simply doesnt work.
