Sometimes the manufacturer's sheets have a password on them which can cause an error when building the package. You could try downloading this file to your computer, "Printing" it to PDF by following the instructions in the link below, and then uploading the clean document to one of your My Folders (also instructions below):

Sometimes "printing to pdf" process will remove the password. Otherwise, feel free to contact the manufacturer and ask them to please remove the password from the sheet.
Regards!
