With 7.1 or 2009, the labels in Facility Manager are controlled from within Facility Manager (i.e. not published from Facility Link). So, the first place I would look is at the labels in Facility Manager. You might need to recreate the label style.
In older versions of FMDesktop, you would publish the labels from AutoCAD, but not in the newer versions. The labels from AutoCAD are actually stripped from the publish. So, if you have no label style set in Facility Manager, you won't see any labels.
There are a few tricks to publish labels from AutoCAD (like copying the label to a new layer and publishing that layer) if that is really what you'd like to do.
