CAM350 netlist verification errors

I am kind of new to CAM350 and having trouble with doing the netlist  verification.
I am using CAM350 v8.6.2

I have imported the Gerber files into CAM350 (using  File/Import/AutoImport).
Run the Draw to Flash, filled in the layer info, extracted the netlist  (Utilities/Extract netlist).
Imported the IPC-D-356 netlist (created by Allegro).

When I do Compare netlist (Analysis/nets/compare external nets), I get  two types of errors.

1) No Copper
2) No Point On Cam Net

I do not understand what the "No Copper" means

Also I have tried to export the Gerber netlist as a IPC-D-350 file  (file/export/IPC-D-350) and compared some of the nets (starting and  ending points) with error 2 with those in the Allegro created netlist.
They look correct (i mean i can look at them with correct positions in  the Gerber files).

Could some one suggest me how to proceed with the "No Copper" error?

Thanks in advance,
