Config file not found

Sorry for the newbie question.
I have this message in my dump.dmp

Config file "D:\02_project\robot\perso\robot.cfg" not found.

Though, the file is in the same directory as the max file I'm exporting.

Therefore, I have these messages from the dump.dmp:

Third pass: Collapsing unneeded nodes...

Removing node "base01"
Removing node "start01"
Removing node "unlink"
Removing node "cam"
Removing node "eye"


Though I have put eye and cam as always export.

Any help ?
