Cannot open .mat files

[AmirHossein207]

I cannot open any of the models in the tutorials or the thermodynamic data file. The error is the same for all
% Not a binary MAT-file. Try load -ASCII to read as text.
and when I use ascii I get this error:
%Unknown text on line number 1 of ASCII file small_ecoli.mat "version".
It seems like I am missing something. could asist me on this?
