Cant get into themeforest account

I have more than 93 themes in my themeforest account and I cannot get into it. I keep going to sign-in and pop up to sign in shows up and then dissapears. What is going on?

hi u should contact the help center they are here for this and no doubt that they will help as soon as they can possibly do …

Its a sensitive issue and they should also respond on forum as well.
