The CPU utilization data shown on the PowerSDR console is a result of a .NET function call to Windows PerfMon.  If the values are not beeing displayed, then the Performance Counter Library values have been compromised and need to be rebuilt.

Follow the procedure below for rebuilding the PerfMon performance counters library for Win7 and Vista:

Click Start, type "cmd" in the Search box.

Right click cmd.exe, and select Run as administrator.

At the prompt, type lodctr /R and press ENTER. (note the "R" is a capital letter)

This will repair the PerfMon pointers (those are stored in the registry).

You should see this message if the process was successful:
Info: Successfully rebuilt performance counter setting from system backup 

"Root Element Error"   reported while starting PowerSDR.  

Solution -  Need to reset the database for that version of PowerSDR.  Reloading PowerSDR will not remove or reset the database,  either remove the file directly or use this procedure.  

Hold the LEFT Shift while double clicking on PowerSDR icon, this should either open the    "Database Reset has been triggered"    message or open the "Radio Chooser" menu.   At the Radio Chooser,  again hold the Left Shift key and double click "Use"  by your radio serial number and then the  "Database Reset has been triggered"  message will appear.      Now select   "Yes"    ..     This will copy your current database for safe keeping on your desktop,  you will then have to re-open PowerSDR,  where it will re-read the EEPROM data and create a new database.  

If this does not work, then download the PowerSDR Master File Reset utility (http://support.flex-radio.com/Downloads.aspx?id=388) 

Run the  PowerSDR Master File Reset utility from your PC and then restart PowerSDR
