FreeFlow Core 6.0.1 SDK returning 500 error

Hi. I'm using FreeFlow Core v6_0_1 SDK to try to access our local FreeFlow server.  The SDK has been installed on the server and FreeFlow has been restarted, and the Simple Workflow is showing up.  When I try to send the KnownDevices query from my PC with the power shell command:

Invoke-WebRequest "http://xerox.imtco.com:7751/FreeFlowCore" -Method Post -ContentType "application/vnd.cip4-jdf+xml" -InFile "C:\FreeFlow Core v6_0_1 SDK\JMF Samples\01 - Client Configuration\01.3 - KnownDevices Query.jmf"

I get the following 500 error

Invoke-WebRequest : HTTP Status 500 – Internal Server Error
Type Exception Report
Description The server encountered an unexpected condition that prevented it from fulfilling the request.
Exception
java.lang.NullPointerException
        com.xerox.gateways.jdfjmf.common.JmfGatewayListener.newMessage(Unknown Source) ...

Any ideas as to what is wrong?

anti-virus removed certain components of FreeFlow Core which caused the problem.
