This mediafire link is fine.  I just tried it.  Could you be more non-specific about what's "worng" with them?

I just downloaded this file again with mediafire.  Didn't see any strings of characters.  Have you by chance recently installed any privacy or security add-ons to your browser, such as ones which disable java or javascript?  In any case, the problem appears to be at your end, so if you'd like suggestions:  
1. If you added or changed anything in your browser lately (IE, Firefox, Opera, Chrome), try disabling that change.
2. If the browser updated itself recently, that could be the cause.  These updates sometimes fix one thing and unintentionally break something else.  Rolling back a browser upgrade is not easy, but if you know how to I would try that next and wait for a newer update before upgrading again.
3. Easier yet, I suggest that people should generally have at least two internet browsers installed on their system in case of problems like this.  See if one works where the other doesn't.  I would recommend in this order: 1. Firefox --the only not-for-profit major browser left, and the one that provides the most privacy and anti-advertising add-ons; 2. Opera --recently sold to I forget who, but not exploited yet; 3. IE or Google Chrome --both brag to Wall Street about equallly about how many different ways they plan to harvest your data and sell it.  Neither IE or Chrom are to be trusted, whatever they promise -as Google recently proved in its Mac version.
