Hello,
I'm new to Revive too but it's very easy to use and works fine out of the box.
I just follow the documentation.
How it works for me:
First I create a Website with different Zones, then create Advertisers, Campaigns (Remnant only with date limit) and Banners, in this order.
Then assign Banners to a Zone. I don't create any Delivery Rules or Limit.
In Zone, in Invocation Code tab select Asynchronous JS Tag to see the code.
Hope it helps.
