Hi Patrick Brill,
Thank you for using our services.
It seems that you need to add a wildcard script map to the ASP.NET isapi assembly. Please refer to attached image on how to add a wildcard script map. The image shows how to add it for the .NET 2.0 version one. However you should reverence the .NET 4.0 isapi assembly.
All the best,
the Telerik team
