B4R Question Arduino upload sketch error

[Beja]

Hello all,
After a long time, today I thought I can play with B4R and used to LED example project. but I got the following error:

avrdude done. Thank you.

And this is the code:

'Using the internal pull up resistor to prevent the pin from floating.
pinButton.Initialize(pinButton.A5, pinButton.MODE_INPUT_PULLUP)
pinButton.AddListener("pinButton_StateChanged")

End Sub

Private Sub pinButton_StateChanged (State As Boolean)
If State = False Then 'remember, False means button pressed.
LightOn = Not(LightOn)
pinLEDGreen.DigitalWrite(LightOn)
End If
End Sub

At first glance, either you have selected the wrong COM port or the COM port is blocked from another application.
Have you installed the USB driver which normally is included in the Arduino IDE software?
Have you tried restarting the PC to free the port?

The Port seems blocked, because the last row says about the semafore. When the Port doesn't exists, the connection is tried a lot of times.
