I've been working with my shake program for a few weeks and just the other day I couldn't get it to open. After tinkering with my new Imac, I found this message; Error: unable to execute UI startup code also theres something about recent script .h missing line 4 and 5. What can I do to get it up and running again. I was working on some light saber effects and in desperate need to finish it. Any help (step by step) that can be useful will be greatly appreciated. thank You
