Unable to download studies from PACS

Hi,

I've been using RadiAnt for years, without problem. It runs on a Windows 11 PC. I store studies on an Orthanc PACS on a QNAP NAS. I downloaded them on local DB for visualisation or comparison...
Everything was working fine for me. But I crated another session on my PC for invited users, and it was not possible to download the studies from this session.
As a matter of fact, I recently upgraded my CPU, and I had to renew my RadiAnt licence because of the hardware change. I did this change on the invited session. It swapped the problem, and I wasn't able to download the studies on my session, while it was possible on the invited one.
I thought it was because of windows access to folders, so I tried to move the DB on Public\Documents, and I even created a new folder on C:\. But it didn't work at all. I changed de default DB on different folders, on different sessions, nothing worked. Worse of all, I can't download studies from any session anymore, despite having reversed the configuration of folders and default DB to the initial configuration!
Can anyone help me?
Thanks,
