Installation super, super operation ..

I bought the stick, so that I can listen to music over Bluetooth with better APTX codec.
Eingesteckt..wurde automatically recognized by bit win7 64 and installed correctly.
After that already installed the included driver CD, thus APTX works.
After pairing then comes the message that I hear now with APTX.

It all comes down as it should.

Addendum: As in other recessions my stick was only a few days and suddenly ceased his duties. This was not the stick but on a Windows update. It simply overwrote the driver. To install the correct driver again went only in this way:

(Click stick)> - Start-> Control Panel-> Device> Bluetooth

In the tab "Driver" -> Update Driver.
Option:
"Browse my computer for driver Soft waiting"
then:
"From a list of device drivers on my computer"

In the list then select the driver that begins with CSR ..

After some waiting, the driver is reinstalled and the key is functioning again.
