Neptune published their official Support portal for the Pine yesterday http://www.getneptune.com/support! This is the best place for support if you need answers or help from the source!
Also, buried on that page are the much requested Windows Drivers for the Neptune Pine! The package was in compressed RAR format- since I’m aware many people might not know how to deal with a RAR, I’ve recompressed it into a zip, located here: Neptune Pine Windows Drivers ZIP
Update: it’s reported that these drivers don’t work, so your mileage may vary. Let us know if they do for you.
