Eeah account or profile can have only one file uploaded. Once you upload your file, you can't not replace it.
If due to an error you need to upload the file again, the only way to do it is to create a new profile under your account, or delete your account and create a new one, then re-upload the file.
If you have purchased any DNA reports, advise us upfront so we unlock the reports for the new account. Contact firstname.lastname@example.org.
