I have a strange problem with my dropn900.

Before it was awsome, i loved it! now it wont start up.

I have tried turning the phone off

I tried uninstalling it / reinstalling using the app manager

turned off and on a few more times but i just wont load.

i get the screen going black and dropn900 loads then it closes and i go back to the main page.

Any ideas? id love to use it again.
