[ASK] Manager error on CFW 3.55 Kmeaw

guys need some help here.

I had been using cfw 3.55 Kmeaw for sometimes and running just fine.

but suddenly this morning when i want to play, all the manager were inside the fixpermission folder, and i can't open my hdd. i don't know where's the error, is it the fixpermission, the manager or the CFW.

if i want to re-install the cfw, do i need to go back to the official os 1st?

what manager works best for cfw.

thanks before
