Using Google Classroom

I have been using and recommending Live Worksheets for many years with the homeschooled students I tutor.  When I originally set up my account I used my personal email.  Now I have a different email for interactions with my students and I have a Google Classroom account with that account.  Because my Live Worksheets and Google Classroom are set up with different emails, I have been unable to sync them.  Am I able to change my email on Live Worksheets?  If I instead create a new Live Worksheets account with my other email, will I be able to move all of my workbooks over?  Thank you for your help and for the wonderful service you provide.
