Following on from this thread,
http://www.boards.ie/vbulletin/showthread.php?t=2056497385, lets try and keep the technical stuff here.
First off, almost everyone seems to be having the step 7 problem. I too had this problem but I eventually got past it. I don't quite know how - I rebooted a few times and also kept prodding the retry button. After about 2 hours it just seemed to work for no apparent reason.
Despite what some posters say over on the BA thread, THE STEP 7 IS MOST LIKELY NOT A FIRMWARE ISSUE OR A FAULT. It looks like it may be server problems at Logitech. There are a few threads on the subject over on the Logitech Forums.
