Could not load file or assembly 'Spire.Pdf' or one of its de

[asanborn]

I'm having trouble getting a site to run using Spire.Pdf. I keep getting assembly binding errors at runtime. Any idea what I might be missing? The license file is included in the build and is in the bin. I've attached an rtf and copied the text below.

Hi,

Thanks for your posting.
I checked that you purchased the license for Spire.Doc Pro Edition. Please ensure you are using correct version of Spire.Doc.
Please confirm if you add the correct reference of Spire.Pdf.dll ,Spire.Doc.dll and Spire.license.dll which are correspond to the target framework of your project, and ensure Spire.doc.dll, Spire.pdf.dll and Spire.license.dll are placed in bin folder of your project.
