BLE_app_lbs not able to flash on nrf51422

[abhijeetpalatkar12]

I have compiled the project successfully, but not able to flash it on nRF51422 development board.

*** error 56: cannot open file
Error: Flash Download failed - Could not load file 'G:\Abhi_nordic_SDK\nRF_SDK_temp\examples\ble_peripheral\nrf51-ble-app-lbs\arm_build\ble_app_lbs.axf'
