Unfortunately, you and many others (Including myself), have purchased a lemon. I have the same problem and have searched high and low for the original drivers for this machine. I have contacted Nextbook about this issue 3 times only to get the same answer.
OK! I finally found what we are looking for!
I have used these files and have FULL function back on my Flexx !!

Follow these instructions:
Everything you need for the Nextbook 10.1 can be found on:
The sensor.7z file contains a registry file which will, after reboot, fix the orientation sensor.
sensor.7z contains the orientation sensor driver and registry config. Run the EXE, then run the reg file, then reboot.
chipset.rar contains the processor and chipset drivers. This enables the SD Card, Touch panel, and other various system resources. Extract, then navigate to ww30PV-with-LED\mrd7-pv-ww30-led\ww30\DriverPackage\Installer\PlatformInstaller\ and run setup.exe.
wifi.rar contains the wifi driver
bluetooth.rar contains the bluetooth driver
These drivers will work on Windows 8.1 and 10.
I used these drivers on my Flexx 11 and restored all functions.
