If you get an error when installing a CIA with FBI,
on the sd card from your 3DS open folder "Nintendo 3DS"
within that folder is another folder with a bunch of random characters, open it
Within that folder is another folder with a bunch of random characters, open it.
Create a folder and name it "dbs" (without the quotes...)
Drag and drop the files from uploaded zip. (title.db & import.db) into the new folder you created "dbs"
(exmaple. "Nintendo 3DS/21301hasd0h21321has0r234wer/213sd64334435501asdaf1h7as0/dps")
Put the sd card back into your 3DS.
Go to your "System Settings", then go to "Data Management", then go to "Nintendo 3DS" then go to "Software"
Let the system fix the files.

Profit!
Feel free to add this to the first post with files. Should help a lot of the newbs ...
