No backend available

Hello,
I have a problem that crazyradio Pa can't comunicate with cf2 in windows (But it was okay when I used it a week ago.). Now, when I run the cflient and click the button of 'scan', there is ''WARNING:cflib.crtp.usbdriver:Exception while scanning for Crazyflie USB: No backend available'. When I run the 'lib-python\examples' program, it also fails to communicate properly 'NameError: name 'le' is not defined, Crazyflies found: No Crazyflies found, cannot run example'(when I run basiclog.py). I've reinstalled the client, reinstalled the driver(libusb-win32,libusbk(now),winUSB,usb serial, all I've tried and I can see in computer management that the driver has been installed correctly), and reconfigured the python environment, but I failed and it also does't work. I really need your help. (The environment: windows10-64bit, python-3.4.5).
Best
Thank you!!!
