Thanks - I've already tried downloading a bunch of times but perhaps I will try from another location?! All other dmg files I have work fine so I'm fairly certain the problem is not OS-related...
In some cases it has taken me 5-10 times to get the file correctly downloaded.
Watch the download and if it stops before it indicates that the size is the same as the one in the link then that one will not work.
