Windows Experience Index Fails

[voyager18104]

All of a sudden I am not able to complete a run of my Windows Experience Index. I get an error message that the Kernel Logger is being used by another process. What does that mean?

Have you rebooted and tried again?

msdn says "The NT Kernel Logger session is an event tracing session that records a predefined set of kernel events. If the session is already in use, the StartTrace function returns ERROR_ALREADY_EXISTS."
