Code interpretation: a question from a MATLAB novice

Dear MATLAB gurus,

I was given a significant bit of code from another University which I was asked to run where I am currently working.  It is a psychology experiment which refers to pictures and sounds, stimuli which I have been given.  So in theory, I should have just had to re-direct the directories and change the port-code. I have downloaded PsychToolbox, which appears necessary for the experiment to run.  When I run the code now, I can't get past the initial text screen ["OK! We are about to begin..."].  Any idea of what aspect in the code is halting this progression?   I realize the code below is a LOT, but, to be honest, I'm pretty desperate, and any help would be much appreciated!

Thanks!
