What would you like to know?

Hi, I'm trying to install or configurate Nimbus/Pretendo, but I'm having a handful of problems in the process.

First, I have to clarify that I have the most recent version of Luma on my New 3DS XL, and the right patches are enabled, so I don't think that's the problem, considering that anything else works fine except this.
I tried to download it and install it from Universal Downloader, but when I open it and press A to select what account I want to load, it sends me back to the menu, if I directly press Y it says the plugin has been loaded, and that I can launch any game from the home menu.

I have no idea if this is how it's supposed to work, but I guess it's not. Because when I go to settings and try to enter on the Nintendo Network section, I just receive the error 022-5432 no matter what I try to do to fix it. I also tried to delete the files and do a manual install instead, but it didn't work either.

I also checked if the files were in the right place, and if there's nothing missing, but to my knowledge everything it's there. I don't know if I'm doing something wrong, or the reason of these errors, but if anyone can help me I would appreciate it a lot, since I haven't seen anyone post a solution to this, thank you before hand.
