You have to format your emuNAND and link your NNIDI installed the (U) NVer CIA with the version in the OP, but I am getting error code 022-2634 (An error has occurred.) when running eShop or other app that requires the NNID.
Follow these steps:
Didn't you format your EmuNAND and link your NNID already?
If you didn't, this is what you have to do (you wont lose anything at all):
1. Backup your EmuNAND using Emunand9 or the Emunand Tool
2. Copy your Nintendo 3DS directory from the SD card to your PC
3. Boot into EmuNAND, open System Settings and choose Format
4. Boot back into EmuNAND and go through setup
5. Go to System Settings and sign into your NNID (now it will be properly linked to the system ID)
6. Inject the previously back upped EmuNAND to your SD card
7. Move the Nintendo 3DS directory back
And there. Your NNID is now active on your system and you should no longer receive the error.
