PERFMON.CONF not forwarding any data to indexer -

[chimbudp]

I have installed Splunk forwarder on a Windows 2003 Server S2- 64-bit
I have set the INPUTS.CONF,WMI.CONF to capture eventlogs,wql results - Working fine

Now , perfmon.conf which i have set is not forwarding any data. 'PERFMON.CONF' file looks like:
[PERFMON:Processor_Info]
counters = *
disabled = 0
instances = *
object = Processor
interval = 300
index = main

Also , i checked the splunkd logs for details : below is the information . Could you please help in identify why PERFMON.CONF not sending any data ?

Log details :
04-04-2013 13:18:52.257 +0200 ERROR ModularInputs - No script to handle scheme "perfmon" was found. This modular input will be disabled.
04-04-2013 13:18:52.257 +0200 ERROR ModularInputs - Unable to initialize modular input "perfmon" defined in the system context: Unable to locate suitable script for introspection.
