Data and Log export settings setup

New to Weather Watcher Live, due to Wunderground ‘playing around’ with their website and PWS owners accessing their own data.

In the Weather Watcher Live setup options for exporting data and logs, whenever I set the export location to anything other than the default C:\Weather option, I get a pop up saying that data exports may not be successful.

I want to export the data and logs to the Weather Watcher Live Data Store folder on my G: drive, as my C: drive is solely for the OS. (Windows 10 pro 64bit)

Why do I get this warning, and can it be safely ignored?
