GPU PerfStudio crashes


I've installed PerfStudio 2.13.1398.0 but can't get any use from it at all...  I'm connecting (port 81), pausing, waiting a few minutes for the "Capturing Frame..." message to go away, but then being rewarded with this blowup in the client:

ArgumentNullException was unhandled

Array cannot be null.\r\nParameter name: bytes

Time spoofing is off, in case that was causing it.  I've also updated my drivers, but to no avail.  This isn't specific to my executable, as it can't handle DirectX samples like BasicHLSL11 either.  Any tips?
