How to overcome this NeatUpload object reference error?

By installing NeatUpload ( http://neatupload.codeplex.com/ ) and put the demo on my server (Windows Server 2008 and IIS7) when I select the object in the combo box for the "execution point 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 any problems.

Here is my installation guide: How to install NeatUpload?

Here is the stack trace:

[NullReferenceException: Object reference not set to an instance of an object.]
   Brettle.Web.NeatUpload.UploadModule.get_PostBackID() +18
   Brettle.Web.NeatUpload.ProgressBar.get_LastPostBackIDQueryStringPortion() +9
   Brettle.Web.NeatUpload.ProgressBar.OnPreRender(EventArgs e) +687
   System.Web.UI.Control.PreRenderRecursiveInternal() +107
   System.Web.UI.Control.PreRenderRecursiveInternal() +223
   System.Web.UI.Control.PreRenderRecursiveInternal() +223
   System.Web.UI.Control.PreRenderRecursiveInternal() +223
   System.Web.UI.Page.ProcessRequestMain(Boolean includeStagesBeforeAsyncPoint, Boolean includeStagesAfterAsyncPoint) +3393

What is missing? I can view the “NeatUpload Console” in order and select the files to upload in order, and you can change the “Send Button Type” without any problems. Also, I never get progress. The only thing I can think of is that my web application is running in .net 2 and not .net 4 - if this is a problem, how can I fix it for the control without changing it for the web application (sharepoint 2010)? Can I have the file in place?
