I had CFW on my o3Ds XL for a few months now and yesterday I downloaded OCDM and MultiDownload++ using fbi to be able to download 3DS Mario Maker levels from others whom posted to SMMDM and tried one downloaded course. I tried to exit to the home menu but I got: An error occured (ErrDisp) Error type: generic Process ID: 67115840 Address: 0x00000cfa Error Code: 0x000000cf Press Any button to reboot. I rebooted and tested other games, I tried Detective Pikachu and got the same error, I tried Miitopia but didn't get the error. I didn't try any other games, emulators, nor apps after that though, I had so many stuff downloaded, but will try them out later. I figured OCDM caused the error but I wanted to keep it so I went to FBI to see what else caused the error and saw two green title ids that had no name of an game or anything else I downloaded and the reset of the info was unknown so I deleted them but I still get the error. Now when I went to go use Miiverse with the Rverse patch, the 3DS screen just freezes when it opens with the miiverse logo, same with the internet browser. I figured it was MultiDownload++ that caused the crashes since it uses the same search tool, but I don't know. Does anyone know how to fix these? (update, I deleted OCDM and MultiDownload++ but still get the errors also my cartridge games crash with the home button)

UPDATE 2: I turned off my 3ds and removed the sd card and turned it back on, I reinserted the sd card and I no longer get the errors

UPDATE 3: I turned my system off and on again to see if it actually worked and now I'm getting the errors. Is there something wrong with my sd card? There shouldn't be, I just got this sd card 2 months ago.
