Just bought the set can not be used as the first, set up as the head of the bright lights can be, how's going on?

The first two days with good, a few days it's no use in the open can not see the image?

No doubt drive Installed.I also ah, ah matter how it is to see if the problem is not the driver.

Added:you try another USB interface! ! ! Feeling that drive, the so-called drive-free does not really do not need to drive, but call the public version of the drive system to work, which requires good compatibility of the song, or a problem is very natural, to recommend Camera and the official website for help to find a driver to re-install the general problem can be solved.
