It doesn't make any difference, 'as i have noted' it's exactly the same .dmg, take a look at the first link on my signature. But if you are so inclined you can redownload the dmg from the said link, you have a big green button that says 'download trial' and below, if you already have an activation key, you have a 'download now' button. The ONLY difference between the two is that the first sends you a trial key by email and the second doesn't, that's it, the download IS THE SAME, anyway, this will get you the latest version.
