Thank you for the explanation, i didn't install it yet, fear of it will ruin everything lols. Actually i have re install the game 2 times, first it is because of acheivement and specialization unlocked in new game, i thought there is something wrong, so i uninstall and re install the game, but still both are unlocked. Later, i know that i will remain unlocked forever. Second time, i don't know how, my antivirus say there is virus at character file, so the game cannot load, i delete the file, i thought it only delete the virus, but it delete the whole. So i cannot play the game, it won't load. So i re install again...lols But thank you for kindness in giving explaation. :) i am 31 years old by the way...
