I presently use Cursor XP Pro. Due to the lousy Michigan economy, I have not been able to renew my subscription with Stardock. I presume I can't therefore freely upgrade to Cursor FX Pro, right or wrong? If right, would I be better off with Cursor XP Pro or the free version of Cursor FX? If it matters, I refuse to run VISTA and still use XP, though I have a free VISTA upgrade sitting on the shelf near me.

Thank-you!
