+## 5 Troubleshooting
+
+1. Have you tried using their example files and running it? You should try this.
+2. Try downgrading your Matlab to 2013b or 2014b (if using 2015, I have tested the code on this and works fine)
+3. Make sure you have installed the `mex` installer and have the `visual studio` before doing it.
+4. I have tried this on Windows 7, may be that could be an issue.
