There was an internal error when querying iis 7.0 for profiling

Question

I have a WCF Service that is running too slow.

I wanted to profile it, so I followed the instructions found here: http://msdn.microsoft.com/en-us/library/2s0xxa1d.aspx

When I try to start up the profiling I get this error:
