Downloaded Dawsonera eBooks now do not open with the normal Adobe PDF reader.
They will have the file extension: .acsm, instead of being .pdf s.
To view these files please download and use Adobe Digital Editions to open it:
Create an Adobe ID at http://www.adobe.com/ and install Adobe Digital Editions on the computer you are using, via the same site. Once this is installed you should be able to view the downloaded file.
Digital Editions has already been installed on all student PCs.
If you are using a mobile or tablet, you can use the Bluefire reader app which is also available at http://www.adobe.com/
