Import Agleader Data

I am trying to import harvest data into Farm Works from my Insite Monitor. Data from the monitor created 32 .ilf files, but when Farm Works looks at it, it only finds 6 .ilf files, and all of those have zero records in them. I am able to import the data into SMS, and my local coop has been able to read them with no problems, but Farm Works finds nothing. I am running FW 2011.9.490 and help indicates all updates are installed. What am I missing?
