I have the same problem. I found a guys name who was with LiteTouch and responsible for my area (PA region) and have left him 6 messages and 3 e-mails over the last three months explaining the situation. No reply. I also then went through their website (Savant's) via the form they have on it to request to be contacted and received no response. I'd be fine spending a few bucks to upgrade our system to the current rev and add some additional functionality, so its not like it wouldn't be worth a return phone call from them.
I have light programming that needs to change and I cannot seem to find anyone who can support the system. I spoken to several electricians who all refused to help. I also called a well respected, high-end home audio/video firm in our area who came out to look at it and recommended replacing everything with whatever they were selling.
I don't want to get ripped off, but I do need some basic help.
