Flare 11 - PDF Stitching Error?

[IHeartTW]

I'm testing out the PDF Stitching feature in v11, and I keep getting the same cryptic error message:

10086, Build failed: Attempt by method 'B3.Pdf2Kit.MadCapPdfWriter.SetFromIPage(iTextSharp.text.pdf.PdfImportedPage)' to access method 'iTextSharp.text.pdf.PdfImportedPage.get_PdfReaderInstance()' failed.

It fails on the PDF target only, works fine in the HTML5 target.

I have GhostScript installed. I've tried different sizes/types of PDFs, but I'm still getting the same error. Anybody else running into this?

I'm also getting this error. PDFs used to build just file. Anyone have a solution?
