ToonBoom Storyboard 1.5 no longer opens

I have Toonboom Storyboard 1.5. However, recently I cannot seem to launch the program. I have tried uninstalling and reinstalling but the same problem occurs. I click on the icon on my desk top and the splash screen appears but the actual program does not open. I am also unable to open any of my past projects. Could you please advise? I have windows 7 and no changes have occurred on my workstation since initially downloading this software (June 2012).

Please contact for this as they will need to investigate what could be causing this to help you resolve it.
