IF you upgrade your Lenz system to 3.6, and you use the LI-USB
adapter, you should upgrade the firmware of the LI-USB. I was having
serious problems before I upgraded.

To upgrade the firmware:

1- Download the firmware code at this link:
http://www.lenz-elektronik.com/pdf/LI-USB-Firmwareupdate-V36.zip
2- Extract the LI-USB.MSI file to your desktop or other locale.
2- On WIndows XP, open the control panel
4- Click on add or remove programs
5- CLick on add new programs
6- Click on CD or Floppy
7- Click next
8- Click browse and navigate to the location where you extracted the
LI-USB.MSI file
9- Make sure your LI-USB is installed and your Lenz system is powered up
10- Click Finish
11- Click Repari LI-USB anwendungen
12- Click Finish

Program should run quickly (~30-45 seconds) and update your LI-USB


Hope this helps someone else.
