I usually get an AIO pack because I don't feel like downloading everything over and over.
One thing I can recommend is getting a spare MSD, formatting it, placing something like underprivileged's AIO (google underprivileged switch), and updating Edizon with the "-" button.
After you know what's wrong (as in, make sure the new MSD isn't doing the same thing as the old one), "replace" (copy to a safe location in case ____ before you delete) those new folders over your old folders, and possibly transfer whatever you want to transfer (other files from old MSD to new MSD), but try not to merge folders--it usually doesn't go very well.
Damn...okay....Do you have a lot of space on your computer?
Honestly, I can tell you updating to the newest Kosmos (15) (I used the built-in updater) to try the toolbox will have no effect. In fact, it'll probably mess up whatever you had in Hekate (depending on your setup).
I'm still looking for the link (and getting angry I keep getting SSA google results).
