I have the same problem.
I tested 0.44.2, 0.46.0 and the latest 0.47.1
I dropped all files from:
C:\Users\<username>\AppData\Local\Alt.Binz
But the same after adding the Alt.Binz credentials without other changed settings or adding the usenet server. Import is not possible with dobble click on the file or using the import function in alt.binz.
I have a copy of the config-files.
In the log tab is only:

Settings->Log->Enable Logging is on
Settings->Log->Detailed Logging is on
The files are correct and locally available.
I uploaded them to my usenet-provider and they can download the files into there cloud where I can donwload it.
I disabled the anti virus tool. The same. It was working in the past.
Any hints?
