Some freestuff items are hosted on sites that have bandwidth limits. when the site runs out of bandwidth then there is a period where it gets reset usually a few hours to a 24hr period. So periodiclly the tumbs hosted on that site and the item are not accesible. hence the broken link icon and no download available. check back a few hours later or the next day. then again some sites just go down and it takes a while for the items to be cleaned out and are just that dead links. least that is what I've experienced with Rend and the free stuff section.
