Make sure you have version 3.1.136. It cured my problem in 10.9 where I couldn't see any thumbnails and had freezing. Some how the program wouldn't show me an update page said I had the latest copy, whereas my copy was 3.0.122.
i just bought acdsee pro 3.1 version 3.1.136 and it freezes after i install the latest maverick OS 10.9. can´t see the thumbnails neither change between manage view or develop option. i tried to reset it and still doesn't work
