HELP! Moved site to new host - Forums/Topics no longer associated with Groups - and CANNOT create ne

I moved my sandbox to a beta production server and in doing lost the ability to create new topics in a group - also - all previously associated topics have disappeared - though I can see reference in the activity stream (on click goes to a 404)..

Am getting this error with each attempt : "This group does not have a forum setup yet."

Have turned off/on all plugins - changed themes - etc for debugging and am still stuck... I imagine that this is database related, but I'm not so familiar as to knock this out...

Also adding to my urgency is that I have a beta team ready to go - and they'll be expecting this basic function to be working...

PLEASE HELP!! (any Obi-Wans out there??)
