The Conga team is aware of an issue with Composer Query Builder not functioning currently and our developers are working to isolate the cause. The workaround is to create queries manually via Workbench or Salesforce developer console. We apologize for this inconvenience and are working to correct and deploy a fix as quickly as possible.
