The school district should have sent an email on your registered email address with the link to returning student Enrollment form. I recommend checking the spam/junk folders of your email. If you have not received an email, I recommend reaching out to the Enrollment section of your school district who should be able to assist you in enrolling your child in school.
Using IE the "Family" information/Contacts page kept freezing. I switched browsers-Chrome worked for me and I was able to submit the form.
To assist you further, would you please provide the details of the difficulty you are experiencing during your kids' enrollment process?
I had the same problem u will actually want to register like normal thru the school district website with a snap code or new student after u get in then you will have the option for online or on campus option. from there you will receive more info if you are a returning student and do not have a snap code contact your school to request it. they will help walk you thru it as well. i hope this helps.
