I don't think he has enough reputation to do that. IIRC, you need to have something like 20 reputation points to do that. I'd up vote the answer to help him out, but he doesn't say what he found in Keil.

Okay, thanks for making me aware of that! I changed it so that the question authors can accept their own answer without any reputation from now on.

I clicked on the tool(Alt+F7) option in keil, selected the "Debug" -> "Settings" option and changed the Port: form JTAG to SW and OK.Then i clicked on"Utilities" -> "Settings" ->Add option and added Nrf51xxx from the list. The error was removed after that and i was able to program my controller.
