Sorry your having this issue. First distinction is that you're looking at Civil 3D labels, not AutoCAD text. When in vanilla AutoCAD, there is an object enabler that allows a flavor of AutoCAD that is not Civil 3D to see the Civil 3D objects. Second distinction, you're working in Intellicad so there would not be an object enabler for you.
Are there other options? There is one more - the person who gave this file should set PROXYGRAPHICS to ONE in the file and send it back, then the civil 3d stuff should be visible without the enabler.
Hope this helps!
Thanks
Kevin
