Hello!
I tried to update firmware 4.06 to 5.1, but I got a message "Error while transmiting firmware"
I have a similar problem when trying to store my settings I did the following:
file---> Transmit all settings from profilux to file
and I got a message "Cannot open parameter definition file ParaList_V4.06_ProfiluxPlusII.def"

I want to update firmware because a purchased two AI sol blue units that I would like to connect to my profilux computer.

Anyone?
