How to Update Neverwinter Nights for PC installed from DVD

I recently found my Neverwinter Nights Platinum Edition DVDs (which includes Neverwinter Nights, Hordes of the Underdark, and Shadows of Urentide) and installed them on my Windows 10 laptop. Since I own the DVD, how can i update to the latest version without having to purchase again through Steam or GOG? The update servers are all down from Bioware and I can’t find any references other than here…
