According to the message, HD is trying to update from the wrong location.
You can try placing this file: https://www.dropbox.com/s/t9vzs83iwmx92fh/%23common.ini?dl=0
in the _HD3_Data\Settings folder.
This file contains the addresses of the update servers. However, it's strange that it "corrupted" (and, especially, that it didn't fix itself after the update). It's possible that the firewall is blocking the download, or the launcher doesn't have the necessary permissions to write files in this folder.
