I have two suggestions if you have installed Kies on your computer and then find that you cannot complete a connection with your Galaxy Player 4.2.
1. Ensure that the USB setting for your player is set to "Samsung Kies". There are three USB settings -- "Samsung Kies", "Media Player", and "Mass storage". Select "Samsung Kies" using the following sequence -- Home -> Menu -> Settings -> Wireless and network -> USB settings -> Select "Samsung Kies". 2. Get the very latest version of Samsung Kies at http://www.samsung.com/us/kies/ . I don't advise using Kies from the Galaxy Player Support web page for the 4.2 because it may be an older version. I used the latest version successfully.
