OpenOffice.org 2.2 failed to initiate

A message ‘The application cannot be started. An internal error occurred’ popped up, and my OpenOffice.org 2.2 failed to initiate (The attached screenshot tells the story).
My operating system is Ubuntu 7.04 – Feisty Fawn. What can I do now?
Does the problem have anything to do with my operating system?
Please extend your helping hand.
