As to upgrading... I am currently trying to exist in this sweet spot where I can continue to run my CS5.5 Adobe Products. Upgrading DNG will require updating my OS which will mean I can no longer run CS. And I am not now, not ever, going to pay Adobe monthly to use their software... I will tear my computer out of the wall, pour lighter fluid on it and ignite it before I do that. So my OS stays where it is for now - and therefore upgrading DNG is not on the radar. But thank you for the suggestion that that is the source of the problem!
