You can only receive one Unity Pro trial for 30 days. It seems like you already used that Pro trial back in October 2009. Whenever you re-download Unity now, the normal, free version of Unity will be available to you. If you would like to receive another trial of the Pro Version, contact Unity Support (support@unity3d.com) and they can probably help you. IF you have any other license related questions, see this forum thread, it contains a wealth of information.
