Hello, I really need help with my resume please.

Hello everyone, so it's been about 5 months since I bought my Vita, knowing nothing about console hacking, I installed pkgj, adrenaline, vitashell and all that.. I played it quite a bit, everything was working well, until yesterday when I decided to remove and reinsert my Sony micro SD to see how many GB I had (8) and since then, big problem, I couldn't launch the games, with pkgj and all the other apps, I kept getting the error message c0-9250-6, which I managed to fix thanks to the internet (I downloaded henkaku) but after that, I could open pkgj and the other apps but not the games, and when I try to open pkgj to install a game, it says "NoNpDrm not found. Games cannot be installed or played." Or if I try to open adrenaline, I get the error message c1-2758-2. Thanks to everyone who can help me without too many technical terms as I have trouble with all that, I would also like to know, if I reboot it to 0, could I reinstall everything from scratch to make it simpler? (I am on version 3.73) thank you all!
