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

Move your nreal folder from your home directory to some other place and try again, maby you wrongly instaled some .h or UI.h macro?
