*iOS
(iPhone/iPad) and Android smartphone users can transfer DRM-protected PDFs
using Bluefire Reader.

Install Bluefire Reader to Sync your device with Adobe Digital Editions.
TSO recommends the Bluefire Reader but as this is third party software we will not be held liable for any technical issues.
For instructions on how to sync your eReader with Adobe Digital Editions please visit the Adobe Digital Editions Help Page.
Can I order PDFs by phone?
The product has to be downloaded online and cannot be ordered by phone. If you are unable to pay by credit or debit card then please contact our esupport team who may be able to arrange a pro forma invoice for payment by bank transfer - details of your download can then be supplied to you by email following receipt of payment.
Can I buy a PDF for someone else?
If you purchase a PDF on behalf of a third party then you will need to supply the intended user with full details of the software required for download and url links for the PDF.
To forward an unopened link to another person by email, right-click on the link and either select 'copy shortcut', or view the properties and copy the 'Address/URL', then paste it into an email for the intended user.
What if I am unable to download?
If you experience any problem with your download then please contact our esupport team; they will work with you to resolve supply of your order.
Are there restrictions for copying or printing?
PDFs are encrypted and will not allow copying, cutting or pasting. Unless otherwise stated the file may only be printed once. Some PDFs contain pages in landscape and portrait. To ensure these print correctly check that 'Auto-rotate and Centre' (if available) is selected on the 'Page Handling' options of your printer settings.
Can I access my PDF on more than one device?
Adobe Digital Editions can be Authorised six times by a single Adobe ID. It is therefore possible to open a protected PDF on up to six different devices by Authorising the software on each device with the same Adobe ID:
- Install Adobe Digital Editions and Authorise the software by creating an Adobe Account (an Adobe ID)
- Download your PDF
- Back-up the PDF to a storage device or system
- Install Adobe Digital Editions on your new hardware system and Authorise the software with your unique Adobe ID
- You will now be able to open your back-up PDF on your new hardware
If you decline signing up for an Adobe ID then your TSO PDFs will belong to the computer and not a named user account/Adobe ID.
You can De-Authorise and Re-Authorise Adobe Digital Editions with the shortcut: (Ctrl-Shift-D for Windows / Cmd-Shift-D for Macs) this allows you to change the ID associated with the software. Please note: De-Authorising and Re-Authorising your software will use one of your six available Authorisation privileges.
What is "URLLink.acsm" ?
If you have clicked your download and received the above
file, this means your PC has not associated the new Digital software required
to receive the document.
Open your Adobe Digital Editions then click on the file 'URLLink.acsm' and drag-and-drop this into the open software window. Your PDF should begin downloading after a few moments.
Who is the 'eBook Vendor'?
The eBook Vendor is Adobe. To Authorise your copy of Adobe Digital Editions simply set the eBook Vendor to 'Adobe ID' and follow the on-screen instructions.

» Your Adobe Software could not be activated. The Adobe DRM Activator is not responding It may be that the Adobe Activator site is busy and you should try later, or that your network will not support downloads from Adobe. In this case please contact your network administrator.

These errors are likely to be caused by a problem in transmitting the required HTTP requests between your PC and the Adobe website. These requests are used to activate your Adobe Reader.
The most likely cause is problems with your firewall or proxy server not allowing these requests through, or otherwise corrupting the requests.
If you are using a company PC you will need to discuss this with your IT department.
If you are using a home PC, you will need to speak to your ISP (Internet Service Provider). More technical support is available from Adobe Digital Editions Help and Support
