Generic Error on System Settings

[empty flax]

So I've been trying to set up Pretendo for my 3DS. Things were going okay when I downloaded from "UNIVERSAL-UPDATER" and hit Pretendo on the Nimbus App.

problem now is; when I go to System Settings it either:
A) Crashes, (see dump image)
B) gives me a generic error upon loading the Nintendo Network ID settings.

For the record, system settings seems to work fine when the SD card is removed. So it doesn't appear that far corrupted. I'm also getting texts on the topside screen saying some RMC addresses are not found. Dunno what's up with that.

At the moment, I'm going to compress my stuff on the SD and put them elsewhere while I try to figure out if I got some sort of conflicting file.

It worked!
Had an unexpected error for a second, but after switching to and fro on my Nintendo account, I finally see this! Wish me luck!
