Can you please email your crash logs to support@inklen.com? Also, it would be useful to see your MixEmergency log file, which can be found at the following path: ~/Movies/MixEmergency/MixEmergency.log (where ~ is your user/home folder) With regards to the crashes, could you try making a backup of your MixEmergency folder (just so that we don't lose anything), and then delete the following files from the original folder: ~/Movies/MixEmergency/ImageOverlay ~/Movies/MixEmergency/QuartzCompositionOverlay Does that allow you to start MixEmergency?
