Never mind.  Somehow the Purchase Code was removed from the settings.  Once I put that in it appears to be working now.  
But now my emails are coning from noreply@testmail.com in Gravity Forms.  When I turn off HMW they use the email address I have assigned in the form. I found where that was coming from in the settings and I changed it but what if I don’t want to have HMW manage the sending email address?  Answer – just leave the “Email sender address” field empty on the General Settings tab.
