Thank you both for your help.
You know, I originally had to buy some points, as I wanted the Red Dead Redemption extra content (in hindsight I should really have bought the game of the year edition). So I dutifully entered my card details, bought the content and had 400 or so points
left over. Then I was informed that the points system was ending, and that my points were being converted back to money (the money I had used to buy them in the first place). Now I apparently only have a set amount of time to use My Money, before it disappears
forever.
I have used a Windows-based PC for eighteen years now, and I have at absolute best a love hate relationship with Microsoft (at absolute best). Their optical USB trackball is a great bit of kit (I have been using the same one for sixteen years now), so obviously
they chose to discontinue it.
Anyway, I am rambling and in danger of ranting. Again, thank you.
