Greetings,

So i just uninstall the game and reinstall it again, but all my data is gone. I already email k-lab and they asked me for data, i write all my data that i can remember but k-lab ask me my friend list and the exact date and time of my registration and last login, i can remember the last login date of my account but not the time :( . Is there a way to find my account friend list or the registration date? Thanks before.
