Hi, I am the creator of RNM and I confirm that it's broken because the project is over since a long time. Gravity has changed the file structure and NIF links to DDS files inside the VDKs after a couple years of updates. And this mod was meant to be working as intended around 2011-2014.
I would have to compile it new again with the latest game data and fix the modded files but I am no more in charge of it. This project is closed since 2014 as I stated it at my blog. I can not guarantee that someone else will take it over and keep the mod up to date unless that someone is a modder who creates his own content.
Also, Warpportal has shutdown the services in May 2018 for the EU players due to disagreements with the GDPR in Europe blocking a huge part of their playerbase in 2018 (unless they use VPNs). I live in Europe too and wouldn't even be able to play under "normal" circumstances and neither wouldn't I be able to test the mod, so R.I.P..

Better some American or Russian (they are not banned in N/A) should be in charge of creating a new mod if it's still worth it, I doubt it though. Sorry to disappoint you.
And sorry for my belated reply, I was for a couple years inactive here.
