How to resolve issue with WMI Exchange Sensor ?

Hello

I have an Error on"MSExchange Store Interface: RPC Latency average (msec) _Total "Sensor for my Exchange 2010. It Returns " The host's WMI system is returning invalid data. Please activate "Write sensor result to disk" in this sensor's settings to find out what is going on. (code: PE264)" Error.

I enabled Write sensor to disk and the below is the result.Please let Me know how I can fix it.
