After trying to start InDesign, I get the 205 error, with a link to a support page.
Following the procedure there (disable virus protection and firewall, change form Firefox to Chrome, deinstall and reinstall in Creative Cloud ) doesn't change anything. Bit frustrating, as reinstalling took at least half an hour (after which I went doing something else). And of course I have loads of work.
Clicking on the headphone icon below ('talking with real people') just gets me back to the same support page.
To contact support follow the instructions given below 1. Go to https://helpx.adobe.com/contact.html?rghtup=autoOpen 2. Wait a bit on the page that opens up, it should automatically open a chat popup. If that does not happen then look for a call out/chat icon at the bottom right, click over it and the chat popup should open 3. In order to talk to a human type "AGENT" in the chat box 4. If you are not able to get to the chat window, then disable your adblockers, firewall, enable cookies/scripts on your browser. If it still fails then change your browser/machine/network.
