I tried this once a year or so ago, but for whatever reason it wasn't able to get through my corporate firewall, while Dropbox was. I am curious if that has been resolved?
I'm stil having the same issue, on the first run it never finishes the 'checking for dinosaurs' part, after a while a warning appears telling me to check if my computer is connected to the internet.
Let's try again and let me know :) Shoot me an email (yuri at aerofs.com) and we can see!
