Your _mmServerScripts files appear to have been out of date.
Make sure you have the latest version of DataBridge installed.
The way I got it working was:
1. I went to the files panel
2. I chose the Remote server
3) I went to the settings menu (upper right corner) and selected View->Show Hidden files
4) At this point it displayed the _mmServerScripts folder so I could delete it
5) I went back and tested the connection and it was working again
