Trying to install using a local/NAT license and am running into the following error

./install.sh kernel=kvm license=VIRTD-XXXXX-XXXXX-XXXXX-XXXXX -email=valid@email.com

And am getting the following output:
ERROR : Email address is not valid. Please give a VALID email address

ERROR :
There was an error while installing Virtualizor
Please check /root/virtualizor.log for errors
Exiting Installer

I should mention, the email address I am entering is the same email address on the account that purchased the license, and failing to enter an email also will not let the install continue.
