We are running NFR Engine 2.0.1.8, PosgreSQL 9.2.1, agent 2.0.1.18.
We are receiving the below error when trying to run File Data reports (date-age, owner detail, filename extension). A directory data summary or permissions report run on the same volume works fine. We are receiving the same error when running against a Netware and OES2 server. File system data scans are running successfully.

Any ideas on what could be the issue?

Exception of type 'System.Web.HttpUnhandledException' was thrown.
