How do I move an application to another device?

---

I have an aviation application I bought 2 years ago and no longer have the media it came on. I moved the application manually from a PPC to my previous phone, a Tilt, and it worked perfectly. I now want to move the application to my new phone, a Fuze. How can I go about doing this(I forgot how I did it before)? Is there any app out there that can do it automatically? I already made the new keys in the registry and copied and pasted the programs whole folder to my new phone but it says my library(in the application) has not been activated. I am at a lose here. Any help would be great! If any more info is needed I can give it as well.

Prolly some dll lost in Windows folder? Really dont think that copying files from on device to other is a good idea, might always loose something in the transaction.
