Is anybody using Parental Link for Fronter?

https://parents.lgfl.org.uk/secure/login.aspx

We want to move away from SLG and have tried to set up this Parentat Link alternative for months now but it doens't work, passing the ball between LGfL and Fronter, accounts don't show up, parent's cant logon and everything is just static

Do somebody has this system working?

Thanks!
