URGENT!! I can't login to my account! When I try to sign in through wordpress, it opens a login form inside the login form and doesn't allow me to gain access. I need to update a clients site...

Hi From yesterday I couldn't be able to either export a theme, update a theme or log in to the Themler app, every time I export or update it asks me to log in if i wasn't logged in so a window pops up...
