Like a previous contributor, I have been unable to download a trial. I disabled popup blocker and firewall, but clicking the 'download' button had no effect at all!
I had a online 'chat' with someone from Adobe - what a waste of time that was. Do these people even bother to read the questions/problems they are contacted with? In spite of the fact I carefully explained the difficulty I was having - i.e. that the download page wasn't working - the link she gave me was for the same page where I'd already failed to download from!
I am having the EXACT same problem! Have tried a lot of times over the past 3 weeks, very bloody frustrating!
I had the same problem trying to download the trial under Internet Explorer 9 (Window 7 64 bit, AVG Free anti-virus software).
When I installed the Google Chrome browser and tried it from there it worked just fine!
