Don't take any of this personally, nyaromulo100. We're a little punchy with this issue. It's actually a little lauaghable at this point. This is by far the single most prolific bug / issue in all of AutoCAD / Civil 3D etc. In fact, some of us have our replies on the ready in the windows clipboard.
Search for "FILEDIA" in any of the AutoCAD based discussion groups and you'll find a mess of 'em.
Of course, not knowing this in advance it's tough for folks like you to find it sometimes.
