I use a very basic docx file in the meanwhile which only contains the names of the var's. That should not be the issue... Howerver, I have uploaded the document for your inspection: http://www.security-blog.eu/wp-content/uploads/2012/09/temp.docx
Furthermore, the first document in the loop is getting created just as it should and based on the (basic or complex) template.
Kind regards,
Johannes
