The recent update to 5.1 has completely stopped working now! Trouble is, whenever you open DxO it says when an update is available and the only way to get rid of the annoying notification is to update it. I'm running Vista and update using he download manager website (automatic update always fails). But even this doesn't work.
I'm going to give up on DxO completely
