Internal Error Please notify the administrator.

Hi to all Experts,

I just successfully run the AddressBook perfectly. I tried to click all the buttons and it's functioning correctly. But when I rerun the application I stacked with the following errors
Please help. Maybe there's a bug in SQLContainer 1.1.0. Any solutions to this problem? Below the screenshot of the error.
