did u happen to update the 3ds to the latest update?
i did and it happen to me too. i got it working again by unistalling fbi(delete title and ticket) and reinstalling the latest update through the homebrew channel with the latest fbi.3dsx
So I did what you said, and it didn't work. I tried to go to titledb in the CIA and 3dsx FBI versions and neither worked. I notice also when I go into freeshop it'll just stay on the loading cache screen forever also. So maybe it's the internet. I'm on 11.7 still. Is there a new version of cttrpwn that works? I could try that I guess
