rubyfocus, - this can happen when the Daz software updates to a new version - it needs a prompt to re connect to the smart content management service.
There are a few things to try - reimport your metal data.
This can also happen if the content management service stops working. There are also 2 versions of the content management service and Daz Install Manager can and will install both - then they confuse each other. The latest is the best and the older one sometimes needs manual uninstall
