Sorry to hear that didn't help!
Hmm, are you aware of any other installed profilers on the machine or any tools that might be constantly profiling your application?
I don't recognize that CLSID, but could you do a search in the registry for 31535964-564b-462a-bf57-f80c986ebe25 to see if you can link it to a particular application?
(Just a note: in the mean time, you should be able to profile using sampling mode or "attach to process")
