XR500 and PureVPN

I purchased my PVN license through Stack Social on a promo.  It came with a user ID and p/w.  Forgot p/w.  Reset it through PVN dashboard and it 'took it' but would not work.  New p/w would not bind to ID because it was issued by Stack.  Had to have PVN set a new p/w from their end and email it to me.  It cannot be changed.  Hope this makes sense.  It was sold by a 3rd party.  It now works w/ a w10 app and should now work on the router.  Have not tried it yet, but expect it to work.  Thank you for you time.  Will give a final update when I get it on the router.  It's a late night here.  Thank you again.
