I was wondering why they sell the new va12a with the vanguard software. Will it work with AHP software with it's new higher resolution? They don't say. What about vista and which versions. Haven't been able to do any updates (still on V2.04) on vista 64 bit system because I get an error saying no va11a attached, it says there are updates available and when pressed AHP shuts down. I would be interested in purchasing their new package but I think these compounding issues will make it very difficult to make it work. Buy it and try it hasn't worked well for me in the past (vista) Once again it seems X10 is going to defer to this forum's members for answers.
