Digital Flow WordPress Popup System is a spin off of Advanced DHTML Popup Pro (ADP Pro, for short), which is a Windows desktop application and web script combination for creating popups. The plugin has only a subset of the functionality of the ADP Pro suite.
You can, however, use the plugin with the ADP Pro suite. Design the popups on the desktop, then FTP them to your website and the plugin will help you with the rest of the configurations.
With the standalone plugin without ADP Pro, you create external HTML files to contain your popup content and link to the files in the popup admin settings.
I only tested the standalone plugin.
Check out the settings page of the plugin–it gives you a good idea of the options and capabilities of the plugin:

There is no way to center the popup in the screen. You can set the coordinates with the top left corner of your browser as the reference point.
One unique feature that this plugin has is its ability to display a different popup per WordPress post. Unfortunately, there is an annoying bug in this feature. You’re asked to choose the desired popup by specifying a #label01. The label is your popup’s ID–you write any where in your WordPress post. When a visitor is looking at your post, the plugin parses the #label01 and displays the popup. Your visitor doesn’t see the label, which is good. But when your visitor is reading your post on WordPress’s homepage, the plugin doesn’t parse the #label01, so your visitor sees it as they see any other text in your post. 
The plugin doesn’t work well with 3rd party email marketing service providers. I tested it with GetResponse‘s web form. The form displayed okay, but the plugin doesn’t know when you click “Submit” so it stays open. I don’t know how to get it to close itself upon submission.
Price, license, and refund policy
The standalone WordPress popup plugin from Digital Flow costs about $25. If you also want to buy the Windows application for building popups, it costs $51. The license allows you to install the plugin on any of the websites you own. You cannot however sell or transfer the license.
If you run into trouble with the plugin, the author will try his best to help. In case he couldn’t help, he will refund your purchase granted you ask within 30 days.
This review is not accurate.
Its a big ding to your credibility to offer such a review and not even have it be accurate.
Anyone reading this review should look elsewhere for an accurate review.
This review is not fair – and I am fully prepared to justify that statement. Mostly this is because it is very out of date
>There is no way to center the popup in the screen.
Not true, and their is lightbox, exit and a preview.
There is also a project management system
Your review essentially says “do not buy this product” and I take this very seriously, given that false information is being provided
And you mention that
“Unfortunately, some stuff was broken along the way. It may still be useful for some marketers”
Again, this is not true, in fact the plugin is excellent after having evolved a great deal in the last year, and is much liked by all who use it.
There has been wide changes since this review and I want you to re-do it, or not review it at all, because as it stands this review is very damaging for the product.
I will do whatever you need to help you re-review it, and I look forward to hearing back from you very soon. I have also contacted you by email,
