I installed that game to both my vita and my pstv. I forgot what it did on my vita, but on my pstv, I had to restart the system first. power it completely off. when I refreshed the livearea again, it appeared. alternatively, u could rebuild the database which means entering the recovery menu. this will remove any app.db mods though, which I have, so I try not to do it unless I have to. if u have no mods, try that. on the pstv, hold down the power button to enter the recovery menu; on the vita, hold R, the playstation button, and then press the power button and hold it 'til the recovery menu appears. then, select rebuild database.
