Why bootstrap sub-theme with sass starterkit is not working? I am trying Bootstrap 7.x-3.6 theme.

But sub-theme for some reason is not working. I did follow the same procedure as described on the Documentation page for Drupal 7. 

I am describing here, what I did,

1. Installed fresh drupal 7.50 on localhost.
2. Down loaded Bootsrtap 7.x-3.6 and enabled but not make is default.
3. Sub-theme: I did copy sass folder from the starterkits. Paste in /theme folder and rename with mysubtheme. Rename the file-name sass.starterkit with mysubtheme.info. And inside that changed the 'name'.

4. Downloding Bootstrap: Downloaded bootstrap file from here as decribed in following image. I did select Sass option. Pasted to /mysubtheme folder, rename with bootsrtap.(even to check, I did try all three options one by one, but same result)


  


5. Downloaded Jquery update module also and enabled, default version was 1.50.

Now, Till this stage the site shows content but not a basic theme formatting. Comparative image below.


  


What could be the reason or I am missing something.
Thanks to @JeffBurnz @MarkCornoy and @FreeRadical for their inputs.

The following setting needs to be disable in mysubtheme.info(sass.starterkit A original file). And may be @FreeRadical want to point out same thing by asking "Have you removed the CDN?" in the his comment.


  ; Disable the CDN provider so compiled source files can be used.
  
  settings[bootstrap_cdn] = ''


After commenting out settings[bootstrap_cdn] = '' it does take the base theme setting.

Any more suggestion appreciated. For now, this solution works.
