Unfortunately, the latest trace has dropped events which make it unreliable for analysis.
I've not seen that error before when starting a trace. Did uninstalling the Precision software require a system restart? I suspect it adds itself as a consumer of system profile events so maybe uninstalling it doesn't cleanly remove itself from that list. I'd suggest restarting the computer and then seeing if you can start a trace with just the command:
[CODE]wpr -start GeneralProfile[/CODE]
