LDD point visibility in Survey 2004

When I open one of my old Autodesk land Desktop drawings in Carlson Survey
2004 the LDD point objects aren't visible on the screen. I didn't have this
problem with Survey XML. In some of these drawings I don't want to just
re-draw all of the points as Carlson point objects because they are large
worksheets with many many points organized on layers. Most of these points
have no descriptors for organizing either since they came from my old cogo
software. So what it comes down to is I'd really like to be able to open
these drawings in Carlson Survey 2004 and have the LDD point objects show up
on the screen.
I heard about object enablers but I'm not sure how to find them or install
them. Any help would be appreciated.
Thanks.....Tom
