I can't seem to get the data to save on startup/reload on startup to work.

I have Windows Service and Starup settings: workspace to load defined as c:\temp\NHCPingplotter.pws. Automatically update workspace on shutdown reboot, checked. Save collected Data on shutdown/reload on startup, checked. Save file location defined as c:\temp\nhcpingplotter

I also have default settings, Autosave checked with a save interval at 30 minutes. Default Filename = $dest $date $hour00

I can see that the workspace c:\temp\NHCPingplotter.pws doesn't appear to be loading at startup. Is there something I am missing or a setting I haven't set correctly?
