Just making this as a sort of PSA, since Kelmych's guide instructs people to use MO1 as the mod manager for Clear and Present Danger. As of today, May 13th, Nexus has disabled their legacy API that MO1, older versions of MO2, and NMM (I think?) used to download mods. I didn't realize this myself until I was trying to find some kind of server outage today when I couldn't log into the Nexus from MO1. I found the Nexus post about the API changes here: https://www.nexusmod...out3/news/14028
I don't know if this is something that a workaround can be made for, but in the meantime you can just manually download mods and drop the archives into MO's download folder in Windows Explorer to install and follow the guide normally from there.
If this isn't the place for this kind of post, feel free to remove it. I just wanted to try and save people the confusion that I already went through.
