Why am I getting an error message?

Error messages happen when your file has become corrupted.

Occasionally you may get an error message  similar to :

” This document enabled extended features in Adobe Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author for the original version of this document.” 

This happens when the file has become corrupted in some way. There are many reasons this can happen, the most common are:

  •  the file has been/attempted to be opened  using a program other than Adobe Reader DC
  • the version of Adobe Reader DC is outdated
  • computer default settings used to open PDF is incorrect
  • There is no Adobe READER DC on the device and another ADOBE product is being used to open the program.

If you get this message or a similar one you can download a fresh copy of the file using the links in the order email we sent you. Alternatively you can email customer support for a new file and they will send it out to you as soon as they can.

Please note that these files are large so if you want it emailed to you promptly check your inbox is not too full especially if using education department emails, or provide an alternative email address.

You do not need to BUY Adobe to fix this issue Adobe Reader DC is a FREE download.
