Cannot load project

Greetings, 
1. I've just started using conn.
2. I'm following the video tutorials using my own data
3. My test project is 5-subjects with 2-sessions (4 runs each session)
4. I ran the preprocessing steps outlined in the first video
5. When trying to load the montage, step-1 of the second video, I get the error below
6. Specs:
<span style="white-space: pre;"> MatLab R2015a (8.5.0.197613)</span>
<span style="white-space: pre;"> </span>CONN v.17.3

<span style="white-space: pre;"> </span>Mac OS: Sierra (10.12.6)
<span style="white-space: pre;"> </span>RAM: 24BG

Any help is greatly appreciated.
