You only need the contents of the syspatchnx.7z zip folder (from the download link at the top of the page, at least on my phone) on the SD card, no changes in the config required as far as I am aware
I had a similar problem as you where after updating the firmware, atmosphere, sigpatches, and Hekate caused a lot of my previously installed games to not work anymore, while others did. I tried reinstalling some of them to no avail, both downloaded NSPs (the ones I tried yielded the invalid...
Yes, that's right. I'm still inclined to think you have old files on your SD card though, so could be a good idea to do a clean reinstall to see if that would help
