I am converting .mht files to pdf. Most of the files work 100%, but some .mht files result in the following error when I call Aspose.Pdf.Generator.PdfAspose.Pdf.Generator.Pdf.Save(memorystream); Aspose.Pdf…...Combine(String path1, String path2)...g path) at System.IO.Path.Combine(String path1, String path2)...
