The dwg is looking for an XREF file and can not find it. You will have to open the dwg and relink the XREF file, then update the dwg within your drawing manager.
If you do NOT have this particular XREF file, you will need to get it from whoever sent the original dwg. Have them send you an etransmit file, this will ensure that you get everything from the original file, i.e. fonts, XREF files, etc.
