X-ATC-Chatter 1.7.1 or older and FS-ATC-Chatter 1.2.2 and older relied on the FTP protocol and a different update server. These older versions of the products will not work with our new dedicated update server which uses only the HTTP protocol.
Update X-ATC-Chatter and/or FS-ATC-Chatter to the latest versions to make use of the new dedicated update server. Should you continue to have problems contact us.
