not contain special characters, blank spaces or punctuation (other than periods and hyphens) in the filename.

If your file is over 25 MB, please employ one or more of the following steps to reduce its size:
Save a clean version of the file by removing any tracked changes. This can be done by "accepting" the tracked changes using the Tools-->Track Changes-->Accept or Reject Changes menu option in MS Word.
If the file is in MS Word format (.doc), try saving it as Rich Text Format (.rtf) using the File-->Save As menu option. If the file is in Rich Text Format (.rtf), try saving it in MS Word format (.doc).
Save the file in Portable Document Format (.pdf). OpenOffice.org offers a free suite of applications (similar to Microsoft Office) that include the ability to create PDF files. Adobe Acrobat is another good option, but isn't free.
