Cannot download ARW file (demo version)
This is not an issue. This is limitation of demo version
In demo mode we force the camera to use single JPEG in single size. We also embed watermarks in final image. In Mac OS X we also change the format of the produced JPEG to TIFF and delete all the metadata from it. Full version will not have any mentioned limitation. We will transmit as many images as you camera produce and in that format that camera produce it. We will not change any metadata in produced files.
