I purge my emails on almost a daily basis. So it's gone. Have the PnP files but didn't keep the password email. My bad. Guess I'm out of luck. Thanks for replying though.
I see David is going to look things up for you, but to note, backer msgs are all available on kickstarter under your account. Click your user icon in top right, then select messages, then scroll down to find the one from David.
