"There was an error opening the file for writing." and then "0x00000001" when restoring miiverse meet.dat file

[NicNamSam]

JKSM cannot restore a Mii Plaza meet.dat file that has been edited in any way, even a single bit. In a previous version, I couldn't even restore a meet.dat file I just backed up immediately before with no changes. In the newest version I can restore a meet.dat file I just backed up, but any editing, either just one bit with a hex editor in the appropriate place in accordance with this walkthrough:

https://www.reddit.com/r/3dshacks/comments/4c5rcp/streetpass_mii_plaza_puzzle_swap_unlock_all/

or with any of the Mii Plaza save editors results in an error.

When I try to restore the edited meet.dat file, JKSM throws the error: "There was an error opening the file for writing." and then "0x00000001"

Have you tried this with the latest version? I cleaned up the FS code for it and fixed a few mistakes. I'm not having problems restoring or backing up the same file on my system using the latest.

I am also getting the same error I am on the latest version and have tried a few other versions but nothing worked

I tried deleting the file on the nand then trying and it worked I guess there was a 1 file limit on the folder
