I've just configured the WLAN connection on my charging station. The wifi symbol is green (proof that the connection is established), but I can't download any files. I tried with a book and a game, but the download wouldn't start. I point the player at the little "start" tab, the player tells me that the file isn't on the player, I put the player back on the dock and... Nothing happens. Any idea where the problem might be? The whole point of this station is that you don't have to download files manually, so if it doesn't work... I don't really see the point...
