Don't worry about the "device not found" exceptions. That's just EFILive looking for additional devices (like an AutoCal device) and not finding any.
After you start EFILive Explorer, the EFILive_Hapi.exe process (i.e. the EFILive Control Panel) should start automatically. After the EFILive Control Panel has started, click on the small FlashScan icon in the System Tray, on the Windows Task Bar near the clock display. That should open the EFILive Control Panel main window. Select the [F8: Trace] tab page and click [Save Trace], then post that trace file.
