MATLAB not saving files

I am having some trouble saving a file.

Here is the code I am trying to save (the custom functions are in the same Documents folder that I am trying to save in):

    syms L ang1 ang2 h d r s x1 y1 x2 y2 A B C D E F G H
  % declare known variables if any

%set up relations
s = 1;
ang1 = 30;
h = 10;
%r = s*(sqrt(2)/2)
%r = sqrt(a^2 + b^2)
%ang1 = 2*asind(d/(2*r))
%L = sqrt((h^2)+(d^2))
%ang2 = ((180-ang1)/2)-45
x1 = s/2;
y1 = s/2;

%rotation of top from bottom
x2 = x1*cosd(ang1) - y1*sind(ang1);
y2 = x1*sind(ang1) + y1*cosd(ang1);

%establishment of joints
A = [x1,y1,0];
B = [x1,-y1,0];
C = [-x1,-y1,0];
D = [-x1,y1,0];
E = [x2,y2,h];
F = [y2,-x2,h];
G = [-x2,-y2,h];
H = [-y2,x2,h];

%label joints
label_joint(A,'A')
label_joint(B,'B')
label_joint(C,'C')
label_joint(D,'D')
label_joint(E,'E')
label_joint(F,'F')
label_joint(G,'G')
label_joint(H,'H')

%establishment of members
plot_truss_element(A,E,'AE')
plot_truss_element(B,F,'BF')
plot_truss_element(C,G,'CG')
plot_truss_element(D,H,'DH')
plot_truss_element(A,B,'AB')
plot_truss_element(B,C,'BC')
plot_truss_element(C,D,'CD')
plot_truss_element(D,A,'DA')
plot_truss_element(E,F,'EF')
plot_truss_element(F,G,'FG')
plot_truss_element(G,H,'GH')
plot_truss_element(H,E,'HE')
plot_truss_element(E,D,'tED')
plot_truss_element(H,C,'tHC')
plot_truss_element(G,B,'tGB')
plot_truss_element(F,A,'tFA')

I try to save, I type in a name, I click save, and nothing changes. The window remains unsaved, and the heading remains as "Untitled*". Any suggestions?

What directory are you trying to save into? If it is under Program Files then you will not be able to save there.

Also, if any syntax errors are showing, you will not be able to save.

same question, r2016a, a blank file cannot save, and typing only

    x=1

cannot save. my workaround is right clicking and saving a new file.
