Well, the thing is that when i was installing ML again, i've finished the tutorial and then it said to put my age, Unfortunately i placed 5 Years old but the truth is that i'm 15 xd, well i wanted if someone can help me, reinstalling don't work, clearing caché and deleting data still don't work. I want to log into Facebook but i can't

Correction: I have 21 years old. I tried to write "I was 15 when i created muy FB acc."
