CrossDomainError means that Cinegy Archive Server (CAS) is not reachable/available. Please check if CAS service URL is set correctly in the Workspace settings.

Also please note: if you use IP address in URL for Workspace launch (in the Internet Browser), you need to use it everywhere in Workspace/CAS settings (CAS service URL, Cinegy Media Service (Thumbnail service) URL, Media URL). And if you use server name - then use it everywhere as well.
