i had to install the original version from google play. then start it so i can login to my account. then exit the app. download and install the blackmod version. install without removing original dc game. start and it should start up. i use ld player. this mod has never worked on my actual phone.
Thank you to explain. I was trying to do it on Bluestacks, but it ever give that Login error. So I tried with LD PLayer as you said and worked but have a problem. Need to do all process again after you close the game.
