Could you please double-check if you have updated both Host and Viewer to the same version 126.96.36.199? Please note that the issue might be caused by the version mismatch, since starting version 7 we've completely rewritten the File Transfer connection mode, so in order for it to work correctly, you need to make sure that your Host's and Viewer's version matches. For more information please see this blog post.
The latest version 188.8.131.52 is available for download on this page. Alternatively, you can also update your Remote Utilities installation via the Self-Update feature.
Please let me know if your Host and Viewer are both of the same version but the issue still persists.
In this case, could you please try the following and see if this helps to resolve the issue: 1. Fully exit the Viewer File -> Exit. 2. Locate the file config_4.xml in the C:\Users\[Your_username]\AppData\Roaming\Remote Utilities Files\ folder. Please note that the AppData folder might be hidden by default in which case you need to enable "Hidden files and folders" in Windows Explorer settings. 3. Remove the config_4.xml file from that folder. This will reset the Viewer settings. Your address books won't be affected by this action, but you will need to register Viewer with your license key once again. 4. Run Viewer, connect to the remote Host and see the issue persists.
