I am trying to download blocks from the site to use in my AutoCAD.  When I try to insert the block I get the error message created with an incompatible version of AutoCAD.  I have AutoCAD 2002.  Is there a way to convert these blocks so I can use them in 2002?  Thanks.

You can convert it with Autodesk DWG TrueView (free).
