LG Vu / CU920 / CU915

alrite i recently put some games in my memory card of my cu920 and there is a problem 👀 . when i install the game, and try to launch it, the game doesnt start 😳 . For some games it freezes on the Java white screen 😕 , for other games (Resident Evil: The Missions) it doesnt even attempt to load the game 😳 , as soon as i launch it, it sends me back to the file directory 😲 . How can i fix this problem? Any help would be greatly appreciated. Thanks 🙂
