Hi John, sorry to hear this.
If you see a yellow warning triangle, it could indicate an issue with a Proxy server or VPN connection.
Can I please ask if you can try following this short guide:
https://studio3t.com/knowledge-base/articles/license-manager-proxy-server/
It’s possible that a change was made on the company network and the URLs that our License Manager uses and that Studio 3T requires in order to connect, have not been white-listed.
We would recommend bringing this to the attention of your IT department, so they can white-list the following URLs:
license-portal-eb.studio3t.com
I hope this helps!
