BB Style :: Access To Text Messages And Emails From Keyboard?

When I click on any email icon and the Text icon nothing happens. Whereas in the past (like even early this afternoon) I would be able to see emails or texts - or if no email or texts it would say 'No messages' - I cannot open either emails or text and therefore cannot create, read, or anything else. The scroll button is inop after clicking on email or text and I must it the exit button to regain control of the scroll button.
