Error message from EMON

Hello all,
I just received a notification of nod32 emon that said that emon could not read configuration during emon execution.
The exact message in french is :
"06/09/2007 11:17:59 - Pendant l'execution de EMON - Moniteur des e-mails Microsoft Outlook sur l'ordinateur XXXXXXXX, l'avertissement suivant s'est affiche: La tentative de lecture de la configuration (5)* a echoue."
In fact I received 5 such a message exactly at the same time but with *(1) to (5)

please does somebody know a little more about this kind of error ? What could have been the possible reasons?
Best regards
