I've been using my leap successfully for the last week or so, but this morning when I tried to connect the Leap, nothing I did would get the computer/SDK to recognize the device. The indicator light on the side of the leap is not lit up. I've tried to plug into all of the different USB ports on my mac, have restarted multiple times, and have tried to uninstall and reinstall the SDK. No matter what I do, the device does not show up in the USB section of my "system information" pane:
Here's my mac version in case that is helpful: 
And the Leap Info:
Please let me know what I can do to get this fixed! I need the leap for a project due next week :0
