SMA Sunny Webbox configuration problem

Anyone have experience configuring a SMA Sunny Webbox?

I just received my Sunny Webbox with bluetooth and two bluethooth piggy-back plus boards for my two Sunnyboy inverters(5000us and 6000us). I installed them and can bring up the Sunny Webbox web page and see both inverters, but they have a padlock next to each inverter and no data is displayed. The Webbox user manual (page 34) suggests that the device password does not match the plant password and offers a procedure to fix the problem. I have followed the procedure, including resetting the device and I cannot get the padlocks to go away. Please help. This is very frustrating.

Thanks,
Randy
