The 'Old Porttest' error message indicates that the feed site PC is running an outdated version of a certain component of Rangecast software, and should be updated.
To update the Rangecast software, launch the Rangecast software (from the desktop icon) and press UPDATE SOFTWARE. When the process is complete, then relaunch Rangecast (again through the desktop icon) and press START.
If this does not clear the issue, then it is likely that a specific file on the PC failed to update. This sometimes happens as a result of certain overzealous anti-virus programs, or perhaps IT restrictions. Rangecast can assist with providing a copy of the necessary file.
