You will need to reach out to BioSig to have them change the email address. Here's the support page link and you will see the support ticket option at the bottom. Do that as soon as possible to ask them to change it.
BioSig is an independent company and not affiliated with Diehl but below is a link to a resource page that has all the info for how to use BioSig.
Good luck with the resource and closing out CE for the year.
