WMI Explorer Performance Counter Returns no value?

I don't think this is a WMI Explorer issue, but I'm curious if anyone's ever had a WMI performance counter return no value. I'm using WMI Explorer to find what I'm looking for, and it seems to work for some things, but not what I'm looking for. These counters work perfectly using Perfmon, so I'm a little confused. How is it that these performance counters can work so well with Perfmon, but when accessed using WMI I can only get the row labels and not the counter information?

Here's an example of my Query

select * from Win32_PerfRawData_TmImssMTA_IMSS

Win32_PerfRawData_TmImssMTA_IMSS?
I cannot find any information about such class. What software provides this class?

Sorry, for delay.
We have installed TrendMicro's Interscan Messaging Security Suite v7 but I still do not see Win32_PerfRawData_TmImssMTA_IMSS class.
Also I cannot find information about this class in TrendMicro's Administrator Guide.
What name space should be used? root\cimv2?

I think I managed to find the issue. Maybe someone here team can tell me if I'm on the right track or not. It think I've learned way more about WMI in the last few days than I ever really wanted to know.

It would seem as though my issue with the performance counters not populating is due to the lack of a "WMI high-performance provider" in the InterScan Messaging Security Suite 7 product. The purpose of this is to provide Perfmon counter information to WMI. This can be seen when running Perfmon in WMI mode by executing "Perfmon.exe /WMI". When run in this mode it's not possible to add the counters I'm looking for, (greyed out) most likely because there's no WMI high-performance provider". Am I on the right track here?

As I know WMI high-performance provider provides WMI counters to applications that work with Performance Counters (WMI -> Performance Counters).
If I understand you correctly you need different option: access Performance Counters using WMI (Performance Counters -> WMI).
BTW: Microsoft does not recommend to create WMI high-performance provider. As I remember they do not plan to support this feature on Vista and Windows Server 2008.

Question is: do you see Win32_PerfRawData_TmImssMTA_IMSS class in the list displayed by WMI Explorer?
If there is no such class, why do you think it should be there? Google cannot find anything about such class.
