Can't log in – Thinkster Math | Learn Math with a Dedicated Tutor Review

Downloaded this for my daughter. Entered the username and id that I logged on with. It states the login or password is incorrect. Please try again or contact support. Does not list a number for contact support or a link to reset password. Totally useless app if you can't log in to use it.
