Issue with "inCommon" Webparts for KN

I have been having issues when acessing KN members pages, errors relating to Portrait in common, contacts in common etc. In the logs it was reporting error accessing perf counter System.InvalidOperationException: The requested Performance Counter is not a custom counter, it has to be initialized as ReadOnly
I actually had an MS person on site with me adn we checked everything in perfmon, no KN Counters to be seen.
I performed a search on the HD on the server to see if the were any DLLs relating to the counters that may not have registerd correctly and came across the following. Funnily enough once I run this it worked OK.
C:\Program Files\Microsoft Office Servers\12.0\WebServices\Shared\KnowledgeNetwork\bin and funnily enough run InstallKNPerfCounters.exe
