The V2 software can cause some issues with Windows 10. You could try the Orion software, in the meantime I'm going to search for the link to the fix. If the Orion software doesn't work, I can't help you.
Edit:
See j-zeitler's post in this topic:
Here is what fixed it for me:
Run:
C:\Program Files (x86)\Leap Motion\Core Services\Drivers\cyfx3.inf
C:\Program Files (x86)\Leap Motion\Core Services\Drivers\ov580.inf
Right click --> install did it for me.
