I downloaded a trial version to test it (And so I'd have flash at home, I need to finish off a big project for monday) and It won't open unless I get a License and it doesn't give me the option to continue trial - though I've only just downloaded it so the trial isn't up? Why is that?
when you install you're offered to license or use the trial. if you select trial and see a message that the trial is expired, there's nothing easy to do to regain the trial, http://helpx.adobe.com/x-productkb/global/trial-software-expired-early.html
Ah, right. Thank you for clearing that up.
