Clickbank Integration works EXCEPT no Registration email is sent

I just can’t figure this out. Everything works EXCEPT the user is not sent the email link to register. Without that email, there is no access.

I get the clickbank test payment email, but the download button just brings me to a S2Member notification telling me that I will recieve an email with instructions… and that email never gets received.

HELP!

Getting the same issue as well.
