NSClient++ Help (#1) - Has listCounterInstances syntax changed in version 4. (#1024) - Message List

Quick question has the command listCounterInstances changed in version 4.

I cannot seem to get the listCounterInstances command to work in version 4 for any peformance counter. The command works perfectly in version 3.

for example

check_nrpe -n -t 60 -H myhost -c listCounterInstances -a "Network Interface" returns "Broadcom BCM5709C NetXtreme? II GigE [NDIS VBD Client] _36"

but in version I (0,4,0,172 2012-05-08) I get the following error

ERROR: Failed to enumerate counter instances: RESOLVER: EnumObjectInstances?: Could not find index: Network Interface : -1073738824: The specified object was not found on the computer.

I know the counter is available though. If I run "nscp client --module CheckSystem --exec listpdh"

I can clearly find the counter "\Network Interface". Any help would be appreciated.

Here is my nsclient.ini
