Mac application quit unexpectedly error

Hi,
My Mac application quit unexpectedly and it said so with this error message below. I didn’t know what really happened.
Tried re-opening the application but the same thing happened. Do I need to uninstall and reinstall the application?
Please help ASAP, I need to resolve this problem immediately. Thanks.

The application TrapLab quit unexpectedly.
Mac OS X and other applications are not affected.
Click Reopen to open the application again. Click Report to see more details or send a report to Apple.
