The last thing I did last night was delete converted videos from my external memory, turned off my IT and charged it overnight. When I got in the office, I turned it on and my main screen was blank. None of my applets were loading. I went through the settings and checked (ticked) my usual applets but after pressing OK, a white window opens and covers the whole screen, freezes the phone for a bit. It allows me to close it via the back button after a couple of seconds.

Any help on whats causing this?

Do I need to reinstall diablo?
