Hello,
For e-Sword on the PC:
1) Download Lange Commentary.exe
2) Open or run this exe file. This automatically installs the module in the e-Sword folder for you. (There's also a zip version, but that's for people who want to manually install it, on a mac or linux).
3) If e-Sword is running, restart e-Sword.
4) Lange's commentary appears in the Commentaries window--that's the top, right window by default. It appears under the tab name, "Lange".
We don't yet have Lange's Commentary for the iPad. I can add that later today. It's a simple matter of converting the e-Sword PC module, using these instructions. The goal here is to convert everything for the iPad app, it's just an issue of time.
Hagmann and Hagmann radio program was talking about e-Sword? When was this?
