LS670ZVJ rooted games crash soon as i start them

[Danny Smith5]

i have a rooted LS670ZVJ as title says i installed some games from app mainia with the app installer then moved the obb files to /android/obb then tryed to start the game and it crashes soon as i click it, i have tryed rebooting, reinstalling, and clearing catch.

my pc dont list internal memory in my computer dont know why im running windows 7 64bit
but i see a android folder in the removable storage when it comes up not sure if thats it or not.

i have modded google play dont remember where i got it the apk file is called www.droidcity.asia_googleplay423installer.apk
games i have tryed are

call of duty black ops zombies
dead defence
dead on arrival 2
future ops online premiume
slender man ch 1
sonic 1 (this one crashes when it loads the first lvl)

EDIT: changed to the google play i found on this site. i cant use root explorer it dont show up in my app installer so i got es file explorer found the files i need for obb but i dont know where to put them when i change to device i dont see a folder called android

Edit: did a factory reset whole phone was being slow. getting ready to install apk files then copy the files to where it says to put the obb folder
