Can’t connect to server

On the desktop version of the software, I can’t connect to the network anymore. I get the message “Communication error. Can’t connect to server. Are you on the internet?”

I can’t sync, I can’t even log out.

I’ve deleted Shot Designer and reinstalled it, and when I launch it it just starts up on the same scene I was on (it doesn’t even ask me to log on).

Could you please help me solve this?
