Arduino Duemilanove atmega32 connection failure

Good day

I am using labview to control a push-pull solenoid via Arduino. i get a connection error that says:

 Error 5002 occured at Ini.vi. Unable to establish connection with Arduino.  Please ensure that you have selected the correct COM port and that you have flashed the Arduino with the correct firmware.

Any idea how i can overcome this please?

Thanks
