Using 'Simple Account Switcher'

EDIT: Back up your act.dat file!!!

I used 'simple account switcher' last night to test if I could use it without issue. After I had switched accounts (worked fine) and then switched back to my normal account I tried running Adrenaline later on.

Guess what! The act.dat was missing. Thankfully I had backed it up on the vita itself to tm0:

So everyone should back up these files before switching accounts! (Just in case)

tm0:npdrm/act.dat vd0:registry/system.dreg vd0:registry/system.ireg

EDIT 2: Pointless to switch accounts or me. Can play games. Can't earn trophies, anyone know a work around?
