No Problem. Just do a clean installation for that game, delete the Game Data and use the latest LV2 Patching... then dont use any BM except Open Manager (Open Manager fully supports KaKaRoTo's Payload... a.k.a. PL3)
Open Manager 2.1J
LV2 Patcher (Kmeaw lv2 Patcher Update) Download the latest *(as of now its v4).
