Thanks for the quick reply! I was able to register successfully with my Apple account email address, and then download, install, and run the beta version (confirmed I’m running 5.0.1b now).
However, despite removing the old version completely, making sure that the beta version is installed in /Applications/Datagraph.app/… and not some other location, I still only ever get a message that says “DataGraph is not running.” when I try to execute any “./dgraphconnect …” commands from the console.
I even tried opening my graph file with “./dgraph <file>” first (which seemed to work) and then trying the dgraphconnect command, and I get the same message. I tried with sudo for the heck of it and that also didn’t work. Am I missing something? Do I need to reboot or do some other step first?
