Script no longer working, help needed

I have a script that I would run to batch pre-process some data that worked well in the past. I had it on another computer running Matlab but recently installed the Student version R2012a on my personal computer. After adjusting the script to reflect the new directories, it no longer works. I'll post the script as well as the error messages (which I can't make sense of), and any help or suggestions are greatly appreciated!

nsubj = length(subject); %number of subjects

for s=1:nsubj

        sname = [pathname_read subject{s} '_KE.bdf'];

        if exist(sname, 'file')>0

            fprintf('Processing Subject #%g : %s part %g...\n', s, subject{s})

            EEG = pop_biosig(sname, 'ref', [65 66]);
            EEG = eeg_checkset(EEG);

            EEG = pop_chanedit(EEG, 'lookup','/Program Files (x86)/MATLAB/R2012a Student/eeglab12_0_2_0b/plugins/dipfit2.2/standard-10-5-cap385.elp');
            EEG = eeg_checkset(EEG);

            EEG = pop_creabasiceventlist(EEG, '', {'boundary'}, {-99});
            EEG = eeg_checkset(EEG);

            EEG = pop_binlister( EEG, '/Users/Myname/Documents/York/KE Monolingual/Scripts/KE_bin_descriptor.m', 'no', '', 0, [], [], 1, 0, 0);
            EEG = pop_saveset(EEG, 'filename', [subject{s} '_raw.set'], 'filepath', pathname_write);
            EEG = eeg_checkset(EEG);

            EEG = pop_basicfilter( EEG,  1:70, 0.01, 80, 2, 'butter', 1, [] );
            EEG = eeg_checkset(EEG);

            EEG = pop_saveset(EEG, 'filename', [subject{s} '_be.set'], 'filepath', pathname_write); 
            EEG = eeg_checkset(EEG);

            else fprintf('\n *** WARNING: %s does not exist *** \n\n', sname);

        end

end

And the error message that pops up after running it:

Any input is really appreciated, thank you!

Never used any of the BDF stuff but it looks like there's a name resolution problem down at the bottom -- the first error is the one about "readlocs() can't find the named file or variable, check syntax" the rest after that is the callback stack back to the calling statement in the script.

What, precisely caused it I don't know but that's the klew...

Thanks, I fixed the first error (my directory for the scalp map was missing a folder), but now when I try to run it I get this error:

Error using pop_creabasiceventlist (line 146)
Argument '' did not match any valid parameter of the parser.

Error in KE_prearf (line 27)
          EEG = pop_creabasiceventlist(EEG, '', {'boundary'}, {-99}, 1);

Have no idea how to fix this as even using the EEGLAB GUI I can't seem to create an event list on individual data. When attempting that, I get an 'invalid file identifier' error. Any suggestions?
