How to Overcome this NeatUpload Object Reference Error?

Having installed NeatUpload (http://neatupload.codeplex.com/), and put the demo onto my server (Windows Server 2008 and IIS7), when I select an object in the combobox for the “Progress Bar Location”, and change it to “Inline”, I get an unhandled exception, Object reference not set to an instance of an object.. I can change it to “none” and “popup” without issue.
