Hi,
I think the problem is with the Adobe download link their download link goes to a server that isn’t in our (Cambridge University) DNS.
Anyway I have the download file now and have installed it. Somebody outside of my Cambridge University domain kindly downloaded it for me and sent it to me via Dropbox, so as far as I am concerned the problem is sorted but Adobe may want to look into this as it should be an easy matter for anyone to download their software.
Thanks,
Simon
