KMKM, yes it's true my hard drive was dead, and I'm sorry I was not in touch. As a point, when you paid the payment page asked that if there were any issues, to leave a message in product support. My hotmail account literally gets 50-100 emails each day, so it's easy for you to slip through the net.
Anyway, your copy has been sent. To be honest, I'm not sure how you managed to pay, as I removed the payment button a few weeks ago!
SOrry for the mixup. If you are still unhappy, please contact me, and maybe we can work out a refund, or some kind of re-embursement.
EDIT.
I just devided the number of unhappy customers by the number of total customers, and it works out that I have a 97.5% customer satisfaction rating, which I guess isn't bad for my first product.
