If you Google there was a firmware update that turns the Control Think stick into a VRUSB. So if you have the Control Think stick, be sure to find the update linked on cocoontech. I'm not sure if the VRUSB had a firmware update or not.
You're problem sounds puzzling if you used the same VRUSB to program a working lock and now it will program a second lock!?! It's nice of Kwikset to send you a second unit for free. I'd ebay both of them and buy a Yale from Worthington Distribution
However, you might try excluding everything from your network, resetting the stick and update to the latest RF Installer Tool software?
PS: The Kwikset only has a year warranty on the electronics. What a joke. So much for me getting a replacement for free.
