Query: not compatible with windows XP...

well since most of us will use this product with XP...considering it is also not compatible with Macintosh either.. I should warn you that after 6-7 hours of screwing around with it, I called customer support and they tried 15-20 different fixes and then came up with... "oh,you have Windows Xp, we have heard from Microsoft and they are aware of the problem but it won't be fixed until the next version comes out and they haven't started writing it yet."I guess it is only if you try to use it with the USB conector but I don't have any serial ports on my laptop so it kinds of leaves me out. I didn't know anyone was using serial ports anymore, even my printer has USB....
