help regarding warning "Configuration Unavailable"

could anyone clarify following doubt?

I have submitted many data sets (.xpt files)  to the Open cdisc validator but it processed only some of the data sets and for rest of the datasets it generated the following message ?

Name        Rule id                      Message

AE:       MISSING_CONFIG       Configuration Unavailable

Could  anyone please let me know what need to be done in this case?

Is there any way that we can make the  open cdisc validator to process these datasets too?
