Default Can't Use My Phone with CM11 For Developing

Hi to all, I wanto to use my CM11 nesus 5 for developing but I've run in a problem. I've activated developer mode on the phone but when I try to start my application from Eclipse I get the attached screen, and the button at the end of the window is disabled, so I can launch my app. other devices with stock android works. CM version is: 11-20140702-NIGHTLY-hammerhead

anyone have a solution?
