isupply3d.com are now selling a Rainbow pack - one reel of each colour including white.The only place I'm aware of is iSupply3D, but they only sell twin packs and that makes it very expensive to buy one of each colour.
Update your PC software to 1.17 from here:Umm.... how do you print at .15? My settings only go down to .2? Does the printer support higher resolutions?

Then update your printer's ROM (be sure the read the instructions on that page and pick the correct ROM file version)
