Try tightening the two gold screws under the battery door near the hinge. The Reuleaux RX Gen 3 uses the metal body for the ground conductor and there are tags under these screws that connect back to the board. In addition to this, download and install ArcticFox firmware. The stock firmware appears to have a bug that, if this connection is loose, is causing the "atomizer short" error message to be displayed.Unless someone has a fix for that
