Hi bpwllc,
I am sorry to hear you are having issues with Auction Nudge. The most common reason for this is because the user has a ad blocker plugin installed in their browser, which prevents Auction Nudge from loading.
This is documented on the FAQ page on this plugin, as well as on the Auction Nudge Help page here:
https://www.auctionnudge.com/help#faq-not-loading
If you are using such a plugin, disable it, or add an exception to see if Auction Nudge loads without it.
If you have checked this already, as you can see from many of the other reviews I provide very quick support for this plugin. I am here to help either on the Support tab of this plugin, or through the Auction Nudge contact page:
https://www.auctionnudge.com/contact
I would be more than happy to look in to this issue further for you.
Joe
