Hey there is a way to work out what your serial no is. In front of you, when you are looking at your computer screen there is a keyboard. On the keyboard you will find keys (strange that, I often wondered why it was called a keyboard!!) Guess what some of those keys make up your serial no. No kidding it really works, I tried it once. I bought this product and with it came a whole series of characters. Some of them were the same as the ones on my keyboard, so I thought to myself. I wonder if I typed those characters in, could I then use my software? I typed them in, and the software works but I still can't use it yet got a whole lot of learning to do.
