1. Download S-89 as pdf from jw org (log in first)
2. Define a custom template folder in TheocBase - Settings, if you have not done so already. See picture ('My Documents' is not a good example, but it is just an example). Attention: At least inWindows the default C:\Program Files\TheocBase\template folder has restricted 'write' permissions. So you cannot use that folder (unless you change the permissions.)
3. Put the S-89 (pdf) into that custom template folder (defined in 2)
4. Open Theocbase and go to print. Theocbase will now do a conversion.
