Please, before you start emailing admin saying that nothing works, please, please, refresh your browsers copy of the website, sometimes the reload button is enough, sometimes you may have to use Ctrl + Reload.
This depends on YOUR settings, or those of your ISP, it’s not something we control.
Also, please check where your download is going And that the location it is going to has enough space.
Downloads will fail if you set, or have set in preferences on YOUR system, to a location that hasn’t got enough space.
Of course when the download fails the best thing to do is blame CML and send me an abusive email.
