The mystery of the failed download hotlinks has been solved.  (Thanks to mrsparky for your insight!)

     My 4shared album is a paid account;  indeed I paid extra for the optional premium service so that everyone could just click on the link and the little save/run prompt box would be the only thing which pops up, no wading through ad-laden web pages.  Well, 4shared has unilaterally changed their terms.  Now, if someone wants to download my freebie, they must register at 4shared and log in to do so.  Needless to say, I won't be renewing this account come December.

     Recommendations for a service which offers direct link downloading (no ads, no redirects to web pages) are welcome.  I'm willing to pay for such an account.  I'm in Ohio, USA.

     Recommendations for the less convenient services (shareCG, et al) are also welcome, since I may not be able to find a direct-link service.
