About 2 upgrades ago, after having downloaded WAZE to my iphone, I tried to log in and when I entered the password, Waze "crashed to the desktop" of my phone. I'm sure there's an appropriate technical term, but essentially Waze closed and returned me to my regular phone icons.

I deleted Waze from my phone and reloaded it. WHen I tried again, the same thing happened.

Is there anything I can do to fix this?
