Default [Q] NBA 2k13 in Samsung Galaxy Wonder GT-I8150


I have samsung galaxy wonder gt-I8150. I upgraded it to a custom rom cyanogenmod 4.2.2 JB. The reason why I have upgraded the android version is to install NBA 2K13. Now my problem is that I have low internal memory but I have an extra sd card of 4GB and I already have rooted my phone and place the obb of nba in external sd card in this path: sd1/Android/obb/com.t2ksports.nba2k13android and already have installed nba but after that when I launch the nba to play, it is looking for some file and trying to download, I think it is looking for the obb file, I am not sure why it can't locate the path of the obb since my phone is already rooted. It should automatically locate the file right or am I missing something?

Your help will be highly appreciated. Thank you.
