Can you download the program nRFGO Studio and use it erase the entire chip? After this is done, you can use Keil to download your application onto the board. I am assuming there is already a soft device on your board and you are trying to write another softdevice onto it without erasing the first one. Erasing the entire chip first using nRFGO should solve this issue.
