This means that Modeller has exceeded the stack space limit. This a 
constant, set when the Modeller binary was linked, so it won't help if 
you add more memory to your machine.

Ultimately, this problem will be fixed by making Modeller use less stack 
space, but until then the simple solution is to increase the stack 
limit. If you have Visual C++ (and know what you're doing) then you can 
use Microsoft's EDITBIN utility to do this.

Alternatively, you can download just such a 'fixed' binary from the 
Modeller downloads page:
http://salilab.org/modeller/download_installation.html
(The link is right at the bottom: "Updated Windows binary".)
Use this binary to replace the existing mod7v7.exe file in your Modeller 
installation (by default it should be in
C:\Program Files\modeller7v7\bin), and all should be well.

If these problems persist, let me know.
