Hello! This plugin is great and I've been very pleased with how it has streamlined my site. There is one glitch, though, that I've run into recently. I have asked guests to enter their email address before they're able to download the file (on the Tracking & Email Capture tab in the settings menu), however if they enter just a first name and no email address and then hit the Download Now button, they are able to download the file. Is there a way to require their email address before the download works?

Thanks!
