Device not found

Hi,
I just bought anew Kindle paperwhite, and have downloaded and installed Calibre 64bit for my Windows 8 64bit machine. I connected the kindle, windows installed drivers automatically, and I ran Calibre. No device icon appears at the top, and when I do the debug;

How can I get my new Kindle to show up in Calibre to transfer my ebooks?
