VerySplitMergePDF can not split PDF file correctly

I am using your verywrite.dll to take the first page of a bunch of pdf documents. I use your VerySplitMergePDF function to do it, attached is a pdf file that was supposed to have nine pages in it but the VerySplitMergePDF had an issue and will not open. This occurs on multiple machines with multiple operating systems. Any help would be greatly appreciated.
