Query: IT DOESN'T WORK

It's no use whatsoever to claim how wonderful this product is and how clever it is to have a pen that "remembers" what it writes, when the damned thing DOES NOT WORK.I'd installed the NET framework necessary, followed all the directions in order (including trying to "train" the pen to recognise my handwriting), and even re-installed the software several times.It DOES NOT WORK.Oh, the pen vibrates and blinks different colours, in the order it's supposed to, as IF it were working, but it does not DOWNLOAD anything.I'd even double-checked that the drivers were loaded, re-set the pen (then did a hard re-set), etc., and all in the right order. And guess what?That's right. It doesn't work.What's the use of having an interesting concept for a product and interesting looking product, when IT DOESN'T WORK?
