I can't remember where I read it but I read that XP works best with 3.0. Vista with 2.0. Not sure where I read it but I have the 2.0 CD. I installed in on 2 different Sony Laptops. 2.0 would not see the ESC but would open with XP. When it opened up the first time it asked to update the software. I did and things worked after that on that laptop. I did the same on my new laptop with Vista. I tried to open the link for the software and a window poped up stating there was an installment problem after I upgraded. I uninstalled all the software from the laptop and reinstalled the CD with 2.0. After I reinstalled it I declined the update. Works perfectly. You might want to find some one in your area or your LHS to see if there is a 2.0 disk some one has for you to borrow. If 1.0 and 3.0 are not working I would say try 2.0. If that fails call Castle directly. It would be a ESC USB problem at that point.
