Can't you just download it from their website so it'll run? I thought that was the idea. I must say, I don't know why it requires a password -- surely the protection is the dongle, not any log-in requirements.

There may be some other codes to it. All dongles are timed, I believe. You could ask them for the program which tells you how many days it has left.
