Error Creating Counter?

Does anyone know what causes this error (Error Creating Counter)

w3wp!library!9!9/8/2005-14:25:27:: e ERROR: Error creating counter. Category: RS Web Service, Counter: Total Cache Hits (Semantic Models), Instance: APPCENTER2005. Error Description: System.InvalidOperationException: Counter 'total cache hits (semantic models)' does not exist in category 'rs web service'.
at System.Diagnostics.SharedPerformanceCounter..ctor(String catName, String counterName, String instanceName, PerformanceCounterInstanceLifetime lifetime)

at System.Diagnostics.PerformanceCounter..ctor(String categoryName, String counterName, String instanceName, Boolean readOnly)
at Microsoft.ReportingServices.Diagnostics.Utilities.RSCounter.Init(String categoryName, String counterName, String instanceName, RSTrace tracer)This looks like a known issue with performance counters not being correctly installed in CTP June and should be resolved in CTP September.
