Can not login my acc

I have been a trader here for a year now. My last successful login was 2 days ago and I have my screenshot. Tonight, I have tried multiple times to login but failed! :( Somehow, my account is blocked now. I am taking Coinspot login errors when I try. Have I tried too many times? That's why? Why I cannot login to Coinspot app now. Please help! I can not find my 12 back-up words either!
