All documents must be submitted in PDF with an extension of "pdf." Two common errors occur: First, a user thinks that they saved the document in PDF. The user then tries to file the word-processing version of the document instead of the PDF version. Second, a user fails to indicate the full path name for the PDF file. Because the system cannot find the file, it responded with the "format not recognized" message. The solution: Provide the full path name when identifying the file during the upload process. Ensure your document is a PDF document.
