Lumia 520, microsoft account doesn't open

[Filipe Lopes1]

So, my phone just went crazy and crashed, it did a reboot, when it started, i saw that the e mail icon was missing, so were my contacts, so i checked the e-mail acc, and when i tried to chose "microsoft account", the screen just blinked and did nothing...
Also, the xbox music, once i chose a song to play, it closes the app.

Reboot again...

If it does not come back to normal, you will have to do a Factory Reset and input your correct Microsoft Account info into the setup again.

Nokia Lumia 520 hard reset

That's exactly what i was trying to avoid... especially since i broke my side buttons, cause they are too sensitive and i change my back a lot.. i also have the latest preview for developers update to download, but it's giving me an error..
thanks anyway
