Cannot delete vault

I have not been able to use my identity vault for a few years, my son thought he would help and put a better password in but forgot to tell me or write it down.

I have tried everything that customer support had me do and even tried to uninstall on 2 other versions of 360 and with Norton security I used the wrong password

3 times and 5 times but the delete vault line will not show up, Do any of you computer experts have any info that would help, I am 51 and memory is slowly going

and I really like having the password vault

Thanks Atticus08
