I am trying to use Premier Elements 12 on a MAC with OSX Maverick latest updates. When I start editing a project the program crashes at some point every single time with the Unexpected Error Has Occurred message. All of my work is lost even though I have named and saved the project. The files used in the project are also missing from Elements. I can't get any work done. I see lots of stuff online about Premiere Elements 11 but nothing about 12. I have work to do and need help fast. I have done a reinstall with my firewall and screensaver off but it didn't help.
try resetting your preferences by holding down shift-ctrl-alt while starting premiere elements 12. if done correctly you'll see a confirmation dialog.
Moving this discussion to the Premiere Elements forum.
On a Mac, that keyboard combination is Cmd+Opt+Shift -- and it must be the keys on the left side of your keyboard or it won't work.
