Query: Does not work with Win 7 pro 64bit

I'm very dissapointed with this product. Other feedback states that this product works with Windows 7. I should have dug further as after spending hours downloading various drivers the product would not work with any of my win 7 64bit machines. [...] has no drivers available and genius-europe site has a "windows 7 driver" but would not work with my 64bit systems.
