For many years I have used Samurize to display this little gem at the top of my display:

Recently I noticed that the meters for network upload and download were not working, so I went into my Samurize config to make sure they referenced the correct performance counters. Unfortunately the "Network Interface" category of performance objects is missing from the list, along with a few others.
The "Network Interface" category is available in the Windows Performance Monitor. I have tried running Samurize as Admin and I have UAC turned off anyway, but nothing has seemed to help.
I would greatly appreciate any suggestions for correcting this!
