FRDM-KW36 Wire ACK Fault in DAP access

I've did some programming on the FRDM-KW36 board. It wasn't really going as planned... Flashing worked fine though. I tried to upload a hello world example sketch to verify that the board was working. I got a error message with the workspace directory so I temporary made a new workspace2 directory, build the example and tried to program but I got a error message... This has been there and I can't do anything now....
