Can no longer see my assets - need help

I recently moved all my Daz folders to a different drive as the other one was getting too full, but now when I load daz studio there's nothing there. Nothing on the smart content bit and nothing in the content library and I have no idea what to do.
Also recieve an error message everytime I open Daz Studio saying:
"A valid PostgreSQL CMS connection could not be established. Several DAZ Studio features that require a valid PostgreSQL CMS connection, such as context aware content views and loading content installed using the Daz Connect service, will not be available. Check your network, anti-virus, and firewall settings for conflicts."
I've searched all over the net for answers and I'm at a loss for what to do.

is the PostgreSQL error new? Did you move the cms folder from AppData?
Have you updated your content paths i DS to reflect the new location - Edit>Preferences>Content tab, click Content Directory Manager, highlght the old path under the current set adn click the Edit button on the left to change it.
I changed the preferences but only some of the content comes up and yeah the PostgreSQL error has only occured since I moved Daz to a different drive
I moved the postgresql folder just now to my new folder but it seems to have made no difference
