Good afternoon to the group.
I have been using NanoVna saver for more than 2 years and upgraded after each new version but left the old .exe files in a folder.
Suddenly, trying to run the .exe files I got an error during the start up prompt screen:: error problem with type - none type has no len.....
or something like that. The screen disappear so fast it is difficult to read error.
This happens with all the versions to my disposal.
Can anyone perhaps suggest a solution. Thank you in advance.
