Re: Lost premium plants.
Starting fresh means Starting from scratch, if you had extra profiles any premium plants bought with cash would automatically be in the new profiles, any seedium or gemium plants would have to be acquired.
If you signed up to EA's email registration scheme you can get a unique code sent to your email address.
Otherwise you will have to contact EA HELP and ask them to restore your account BUT you will have to provide them with your old player id number, I hope you saved it.
