Adjustments embedded in DNGs are Adobe only - Adobe doesn't document how to encode adjustments, so its highly unlikely that C1 will ever support DNGs with adjustments.
Your options are either to export in a non-raw form, e.g., TIFF, or try CornerFix, which does more or less what C1's LCC process does directly on RAW DNGS, but by adjusting the actual raw data, not by embedding adjustments.
