Superpad 2 error message?

I am using a tablet PC called Fly Touch 3 Superpad 2. It is a 10.2 Inch PC with resistive touch screen and uses Android 2.2 OS. . It gives an error message "The process android.process.acore has stopped unexpectedly. Please try again". On pressing force close the computer continues to work. After some time again the same message is displayed. Any solutions ?
