Works after installing 5.2b1 and b2, but after a restart of the computer, you can no longer get it to work.

Under b1, you can uninstall the driver, and reinstall it, but it still does not work.

Under b2, you can uninstall the driver, and reinstall it, and then it works again, until you restart the computer.

RC is the same as b2

Works in release version, thanks for the updated driver.:)
