Hello @DSperber,
The error 2002 indicates that our update servers are in the middle of the synchronization process.
This might be caused by a slow internet connection. I would recommend contacting the Technical Support Teams, as more information might be required to troubleshoot this. They can also request logs from you this way and test the internet connection to see if this is indeed the culprit.
You can get in touch with our engineers by choosing one of the contact methods available here:
