0 lights error?

[tplarkin7]

I get the following error in one drawing upon opening it (AutoCAD 2009):

AutoCAD menu utilities loaded.
Render API error: Invalid light name: "".
0 light(s) were found and converted to the new format.

The only annoyance is that it prompts me to save when I close out, even when I didn't make any changes. I don't know if this will interrupt publishing.

I've tried purging and auditing, but no success. I've also tried viewing the lights, but there are none.

Note: I'm working with AutoCAD 2000 drawings, but using AutoCAD 2009. I have 2009 set to save as 2000.

Thanks for any help!

Maybe it's the fact that you are saving from 2009 all the way back to 2000.

Try this. Save the drawing (using "saveas") in 2009 file format. Open the drawing. Do you still receive the same error?
