Hello Carl,
Thank you for the clarification.
Please make sure that you're running the latest version of RU Server
3.2.1.0 which is available for download on
this page. In case if you're running an older version, please try updating your RU Server to the most recent version and see if the issue persists.
In case if using the latest version doesn't help, please also try the following:
1. Backup your RU Server settings and data by copying the folder
C:\Program Files (x86)\Remote Utilities - Server\ and the registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Usoris\Remote Utilities\MiniInternetId on your Server machine.
2. Then try fully uninstalling your RU Server as described in
this guide.
3. Make sure to restart your RU Server machine and re-install your RU Server from scratch following
this guide.
4. Restore your address books and Server's settings from the backup created on Step 2 by following
this tutorial.
5. Make sure that your RU Server is registered with the correct license key as described
here.
6. Try running RU Server once again and see if this helped to resolve the issue.
Let us know if the above worked for you or if the issue still persists.
