Erm... bought dongle at Tesco in UK for about £10. Software on a cd in the box which installed without incident (ver 5.4.277.0). Connected dongle to Apple keyboard (win 7 PC) and it works great. Was checking to see if there was a software update and seen all these negative comments and thought I would try and redress the balance a little. My advice, buy from a shop... you can always take it back!
